* Do not walk modules every time on `getMappingFor`.
* Ensure that all `getMappingFor` methods return same mappings.
* Remove duplicated methods from DefaultVcsRootPolicy.

We will override existing mappings in `myMappings.setDirectoryMappings()` anyway.

* Avoid unnecessary "AbstractVcs -> Name -> AbstractVcs" conversions
* Do not ignore exceptions

PY-33673 AttributeError: 'FigureCanvasInterAgg' object has no attribute 'renderer' when trying to save plot to numpy array.
