The `git submodule status` command is relative to the current git repository by default.
When running from a repository subdirectory paths can be returned above the current directory.
Specifying the current directory with `git submodule status` avoids listing submodules above that directory.
This will fix issues when testing a collection that is rooted below the repository root when that repository uses submodules.
