Make group transients transient only for windows in the same group that

were mapped before it, not for new ones. This greatly minimizes
the posibility of loops and avoids all those problems in #67914
causes by so many dialogs not having their parent specified.

In the case of group transient window, Client::transient_for is NULL,
and Client::groupTransient() returns true. Such window is treated as
if it were transient for every window in its window group, with the exception
of the windows that are (even indirectly) transient for it (quite nasty,
loops must be avoided).
if it were transient for every window in its window group that has been
mapped _before_ it (or, to be exact, was added to the same group before it).
Otherwise two group transients can create loops, which can lead very very
nasty things (bug #67914 and all its dupes).
Client::original_transient_for_id is the value of the property, which
may be different if Client::transient_for_id if e.g. forcing NET::Splash
