Fixing failing tests in Aeras.  Looking at the tests it appears for most of them
the input file was copied from another problem, hence the regression tests failed.
I have rebaselined them to be specific to the problems.

For other problems (XZScalarAdvection and TC2), there were slight changes in the responses
from what they were before.  Examining the solution / input file changes, I've determined
these are reasonable and rebaselined the tests accordingly.

TC5 is still failing due to a seg fault at the end of the run, which I am investigating.
