Handle windows paths in workspace.get_uri_like + test (#87)

* Handle windows paths in workspace.get_uri_like + test

* Guard against module_path=None being passed into get_uri_like

The assumption is that the definition points to the current file instead

* Also quote outgoing uris

* Make sure a colon exists before trying to split a windows path
