Use mDatabaseManager when calling database functions

When Bluetooth is turning off, there were cases
that getConnectedPolicy() or setConnectedPolicy()
of ProfileService are called, which threw NPE as
mAdapterService is null.
This CL adds mDatabaseManager to profile services
so that they can handle those cases.

Tag: #stability
Test: atest GoogleBluetoothInstrumentationTests &&
manually turning on/off Bluetooth
to confirm NPE is not thrown
