Transition events drop when changing navigation during pause

[bemson]

Panzer lacked the unit tests to show how pausing during an "out" phase (and most likely "in"), triggered several issues. Namely, skipping traversal events, like the "in" phase of the target node - specifically when a sibling of the paused node.

This ticket tracks commits that prove the issue (along with some updated unit tests). The fix was that the resuming flag had not been considered for the "in" and "out" phases.

This addresses bemson/salt #83. The fix will lead to a patch version bump.
