This moves the MIMA checks to before the full Spark test suite such that, if new PR's fail the MIMA check, they will return much faster having not run the entire test suite. This is preferable to the current scenario where a user would have to wait until the entire test suite completes before realizing it failed on a MIMA check in which case, once the MIMA issues are fixed, the user would have to resubmit and rerun the full test suite again.

12b0aee [Brennon York] updated to put the mima checks before the spark test suite
This PR allows SparkQA (i.e. Jenkins) to report in its posts to GitHub what category of test failed, if one can be determined.
The failure categories are:
* general failure
* RAT checks failed
* Scala style checks failed
* Python style checks failed
* Build failed
* Spark unit tests failed
* PySpark unit tests failed
* MiMa checks failed
This PR also fixes the diffing logic used to determine if a patch introduces new classes.
