Embedded entities which contain a empty collection of values that aren't entities are now considered empty, if this collection is empty.
Closes#1737

In an aggregate A->B-Collection<C> a select gets executed for loading Collection<C>.
That select used the wrong ID when B had an ID with the same name as A.
This is now fixed.

Let the AggregateReference converters now receive also custom converters as delegates.
Remove the ArrayToObjectConverter which just uses the first element of the array from the DefaultConversion service.
This does NOT solve the underlying problem, of having two DefaultConversionServices at work.
One is in the store conversion, one constructed in the AbstractRelationalConverter.
Although it looks like they get merged, the former contains converters, using that ConversionService as a delegate.
Attempts were made to move AggregateReferenceConverters out of the store converters and just register them directly,
but then no custom read/write targets are detected, leading to failed conversions.
The same problem prevents a registration in CustomConversions as a Function<ConversionService, GenericConverter> or similar, which would allow late registration.
The problem here is that custom read/write targets require the function to get evaluated, before custom read/write targets can be determined.

createPersistentEntity(..) effectively only calls the overriden method.
It therefore can be deleted.
Remove error message no longer used.

Introduce caching for configured RowMapper/ResultSetExtractor.
We now create RowMapper/ResultSetExtractor instances only once if they are considered static configuration.
A configured RowMapper ref/class is always static.
A configured ResultSetExtractor ref/class is static when the extractor does not accept a RowMapper or if the RowMapper is configured.
Default mappers or projection-specific ones require ResultSetExtractor recreation of the ResultSetExtractor is configured as Class.
Reuse TypeInformation as much as possible to avoid Class -> TypeInformation conversion.
Introduce LRU cache for DefaultAggregatePath to avoid PersistentPropertyPath lookups.
Introduce best-effort quoted cache for SqlIdentifier to avoid excessive string object creation.

When the child of a one-to-one relationship has an id, the value for that id gets read in the wrong way.
We get the column name for that id use that to access the value in the RowDocument.
This results in either no value at all being found or even worse, the value of a root entity with a property of same name being accessed.
This is fixed by using the full AggregatePath instead of just the property for accessing that value.

Construction of the back reference assumed that the table holding the parent of the foreign key is the actual parent property.
This is now corrected by using the correct API to identify the ancestor which holds the id.
