IssueShow and TrackerShow :: UnitTests

Added the above unit tests still incomplete in terms of coverage.
Haven't really touched e2e either passes on my comp but may be in error.

The diffs to the other files should be okay.  I had to change the newest version of trackerShow since it started failing  my tests after the most recent merge.  Basically just moved all of the variable declarations to the top of the method.   Tests were complaining about variables being used before the were declared or initialized.
