ZF-10049: Initialize Zend_Db_Table_Abstract metadata cache for the resource multidb


The same feature ZF-10033 for the resource multidb.

Maybe we can modify the name of this method to be more clear like _setDefaultAdapter() or _setDefaultDb().

Contrary to the resource db, I write my method as protected to be in harmony with other setter.


Fix the compatibilty of unit tests with a case sensitive filesystem.

Fixed on trunk six days ago.
