Only run git_deconfig if Git configuration exists

Browse Source 
This will let us run 'git lock' even if no filters are configured.

This logic is more complicated than I would like because running
'git config --remove-section' on a non-existent section results in
a noisy error (with text printed to stderr and an exit code of 128)
instead of a quiet error like the other 'git config' commands.
