Fix unit tests with TrackPathDescriptor.

Browse Source 
In MapOverlay, for testing, expose a getter and a setter
for TrackPathDescriptor instead of newPath and getLastPath.

In SingleColorTrackPathPainter, refactor "new Path" to a
newPath method so that tests can override the newPath method
to provide a mockPath.
