improve findPythonDeps to recognize non-canonical package names

For e.g. `ruamel.yaml` the canonical name is `ruamel-yaml`
but the package name as recorded is still `ruamel.yaml`.
So if the search using the canonical name didn't find anything try again with
the original name before failing.
Tested on `maggma==0.60.2`
