Permission check for ConnectionService PhoneAccounts. (1/2)

Adding permission check which ocurrs when registering a PhoneAccount.
The permission ensures the ConnectionService for the PhoneAccount
has BIND_CONNECTION_SERVICE permission.
Removed lookupServices method in ConnectionServiceRepository,
which was unused.
Set TestConnectionService service permission to BIND_CONNECTION_SERVICE.
