commit: fix regression on "creating new head" message being shown when
is not actually the case

Revision 5b48d819d5f9 introduced this problem, and introduced changes
basically performs
the check "if all your parents are not in branch heads, then show the message".

Heavily guided by tonfa. Thank you.

Also adapt tests to pass. Here subrepo was expecting an extra "created new head"
