Fix incorrectly named integration tests

There are a few components with tests not following our naming standards (*Test.java for unit tests and *IT.java for integration tests).

They need to me renamed to ensure they run with the appropriate plugin.

The component camel-salesforce also contains some tests named using *IntegrationTest.java pattern, but that component configures the failsafe plugin accordingly and has a build and setup process that is significantly more complex than the typical Camel component.
