RecordStore: Minor improvements and adjustments

Stub enumerateRecords with tags, remove a null pointer check when
creating a new enumeration (jars like to do this), and rewrite
RecordStore's own null pointer check (this one has to stay, as
creating a record store from a null name shouldn't be supported)
