Attempt to fix build; after_test "executed with exception"

I'm a little confused as to how this happened.  It could
relate to an exit code sent by SonarScanner.

I'm going to combine these two commands into a single step
so that if SonarScanner drops a non-zero exit code, it should
still continue on past it.
