MOTECH-1165: Clean up integration test executions

We now only have one failsafe execution for ITs.

Included files are:
- *IT.java
- *IntegrationTests.java

Excluded files are:

- *BundleIT.java
- *ContextIT.java

This means that tests that should be ran as part of Suites
should have names ending with either BundleIT or ContextIT.
