Issue 5736: Fix input/regression/context-find-parent.ly (issue 559460043 by address@hidden)

[nine . fierce . ballads]

Reviewers: ,

Message:
Regtest differences attached to the ticket are expected.  I would
appreciate independent confirmation; is anyone interested in taking a
little time to understand the case? After that, I think it will make
sense to push this, since the code was reviewed last week and is just
enabled by this patch.

Description:
https://sourceforge.net/p/testlilyissues/issues/5736/

Enable the previously reviewed block of code required to fix this
regression test.
