`bender clone` on Path Subdependencies Fails

[da-gazzi]

If a Bender repo A contains a subdependency B, specified in its Bender.yml as a Path dependency that is located in a subdirectory of the repo with its own Bender.yml, bender clone B -p my_local_stuff fails with the following error message:

error: remote source already exists.
error: git renaming remote origin failed

I assume this is because Bender assumes that B is also a git repo, but it isn't.
My proposed solution would be to treat Path subdependencies slightly differently:

• bender clone A could update Bender.lock (and Bender.local?) not just for the A dependency but also for all Path subdependencies of A, pointing them to the clone'd local version contained in the clone of A.
• bender clone B could fail and tell the user that B is a Path subdependency in A, and they should bender clone A instead.

Path subdependencies are currently not handled well throughout bender. #225 adds an error when attempting to clone a path dependency to avoid the issue you are facing. Future updates to how path dependencies in git dependencies are handled can be tuned to ensure this issue is properly addressed.
