Made the sorting in getSchemas per default by name.
Fixed migration with TRIGGERs.

DDL with TRIGGERs aren't possible with prepare statements. Removed prepared statements in migration commands.
Fixed bug with hydrating objects that belong to another object through a many-to-one relation.

This bug only occurs during disabled instance pooling, since the TableMap::populateObject returns
always a new object and related objects (one-to-many from this point of view) are each attached to
this newly created object, which results basically in wrong getXYs returning always one object.
