set_roll_back should only rollback initialized connections

Browse Source 
The exception handler call "connections.all()". This creates a database connection to all defined databases. 
As a small optimization you can use "connections.all(initialized_only=True)" to rollback only the database to which the current thread has open connections.

(My application can have many databases defined, and this loop is identified as a source of many idle database connections)
