fix crash when creating subgroup-bus - fixes #6642

Browse Source 
the actual issues is in the connection management:
bundle.cc:323: void ARDOUR::Bundle::connect(): Assertion `N == other->nchannels().n_total()' failed.

That could be resolved. However, combining tracks without panners will
almost never do what the user really wants, so this case has been 
disabled for now.
