Incorrect path in new_local_repository causes Bazel crash with unclear error

### Description of the bug:

Specifying the wrong `path` with double slash at start or in middle of path in a `new_local_repository` rule causes Bazel crash. The error message is:

`FATAL: bazel crashed due to an internal error. Printing stack trace:
