When typing `tutor local run --mount /path/to/edx-pl<TAB>`, the mount option should be auto-completed to the full edx-platform repo path. That is, if shell completion is enabled: https://docs.tutor.overhang.io/install.html#shell-autocompletion Here, we make sure that the implicit form of the `--mount` argument is properly auto-completed. We are unable to get completion to work in the explicit form, because args that include colons do not even reach the `shell_completion` method.
