branch: add test for -m renaming multiple config sections

Add a test for how 'git branch -m' handles the renaming of multiple
config sections existing for one branch.

The config format we use is hybrid machine/human editable, and we do
our best to preserve the likes of comments and formatting when editing
the file with git-config.

This adds a test for the currently expected semantics in the face of
some rather obscure edge cases which are unlikely to occur in
practice.
