t/config_limiter: fix check for identical Git object

If we completely undef an object, it is likely possible
to have the same scalar address as the original object
even if they are different.  So keep the same object
around and only force creation of the same reference.
Tested on Perl 5.14.2 on Debian 7.x wheezy.
