Further refinements to the CheckSourceTree test.

Echo results of calling git status before exiting with
an error. Add one special case so that the test may pass
on the dashmacmini2 continuous dashboard, despite a 'git
status' non-zero return code. More logic like this may
be required. I will re-evaluate based on tomorrow's
nightly dashboard runs.
