t3200: unset core.logallrefupdates when testing reflog creation

This test checks that the "-l" option creates a reflog. But
in fact we'd create one even without it, since the default
in a non-bare repository is to do so. Let's unset the config
so we can be sure our "-l" option is kicking in.

Note that we can't do this with test_config, since that
would leave the variable unset after our test finishes,
confusing downstream tests (the helper is not smart enough
to restore the previous value, and just always runs
test_unconfig).
