Tests can fail due to .config/pkgdev/pkgdev.conf modifications

[anthonyryan1]

I observed that if I run pytest within a fresh git clone of this repository, some tests failed.

I realized this is caused by the tests still using my .config/pkgdev/pkgdev.conf file while testing.

The following sample pkgdev.conf file demonstrates the problem:

[DEFAULT]
commit.signoff = true

Which leads to TestPkgdevCommitParseArgs::test_commit_signing && TestPkgdevCommitParseArgs::test_git_commit_args_passthrough failing.

Not urgent, because it's easily worked around by removing that argument from pkgdev.conf. But we've got outside environment leaking into tests and causing issues.
