fix(tests): disable gpg signing in test repos; fix warning to use relative path

The global git config had commit.gpgsign=true which caused all BDD test
scenarios that create git repos to error with a signing server failure.
Setting commit.gpgsign=false locally in create_repo() lets these tests run.

Also corrects the 'Only considering files in' warning to show the
relative path rather than the absolute resolved path, restoring the
expected output for the multi-directory src filter scenario.
