Title: Fix unit tests for find_in_workspaces and minor improvements

Changes the unit tests after find_in_workspaces API has changed

Note that a slight semantic difference exists due to the refactoring in Dirks commits: if a workspace source location does not contain a project, it now is not listed in considered_paths. Not sure whether to consider that a bug.

Also note that when a path but no project is given, the source locations are not searched (still not sure whether this combination is valid, and whether the non-search is a bug).

Else added commits for better default behavior when client code passes search_dirs=[], and to not print an empty line when no results were found.
