A major milestone: all unit tests now pass when run externally.

- Fixed an important bug in addNode, a helper of createOutline: There was a confusion about commanders: p is in the old commander. p2 must be in the new commander.
  As a result, nodes are now copied to the top-level of the dynamicUnitTest.leo, just as in unitTest.leo.  This makes a difference for some unit tests!

- Disabled a few unit tests when run externally: This was typically due to missing nodes or copies of clones not being cloned.
