Refactor convertAndAddParameter method to writeValue(…) decoupling responsibilities for a clearer value conversion code path. Also, refactor collection conversion to functional callback-style and extend test assertions.

JdbcRepositoryEmbeddedIntegrationTests no longer runs for all databases, since it doesn't tests anything specific to differen RDBMSs.
Therefore the test also got renamed.
See #1565
The reason for auditing to not work on embedded fields is that EmbeddedRelationalPersistentProperty and BasicRelationalPersisntentProperty were not considered equal even when they represent the same field.
Note: the fix is somewhat hackish since it breaks the equals contract for EmbeddedRelationalPersistentProperty.

We now use one pooled `DataSource` for Oracle.
This should avoid problems with the TNS-Listener, which seems to have a problem with constantly opening and closing connections.

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

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.
