[PATCH 6/6] t7420: Test that we correctly handle renamed submodules

["Jan Alexander Steffens (heftig)" <heftig@archlinux.org>]

Create a second submodule with a name that differs from its path. Test
that calling set-url modifies the correct .gitmodules entries. Make sure
we don't create a section named after the path instead of the name.
