Collection support for predicates on meta fields. (#1338)

Browse Source 
When a derived query is being created and there is a predicate on
a meta-field ( meta().id, cas, expiry), translate that field
(i.e. id -> meta().id) *without* the bucket or collection name,
as it might apply to a collelction which we do not know yet
(for instance, if there is a withCollection() specified)..
This is fine, because in a derived query, meta() without the
bucket or collection name is unambigous.
