Bug 6713, editing matching rules broken

Bug 6713, editing matching rules broken

Was a template error, but also a bug that had been in there for a
while fixed too

Please test by editing a matching rule, match sure no new match checks
are added, and that the matchpoint components survive.

Then try importing some marc records using that match rule
