The problem here is that we will need to create a small static
git repo somewhere first, relying on the mozilla one causes
other tests to fail due to timeouts and makes the test run VERY
long
* Always remove the repository directory.
* When testing recursive with git 1.7.9.5, we cannot test for a directory because it's a plain file with the contents:
gitdir: /tmp/salt-tests-tmpdir/salt_repo/.git/modules/vendor/modules/js/receiptverifier
* don't overwrite or delete when the force option is not true
* when the user `runas` doesn't have permission to create a directory in the
parent directory of `target` or `name`, the directory may be created in
preparation of git. So, don't remove the empty directory before cloning.
* the force option still removes the directory even if it is empty
* ensure submodules are initiated recursively everywhere for consistency
* catch all module calls for consistency
* tests to test
