Actually run the SwitchProducer tests

[makortel]

While doing something else I realized that in #25439 I forgot to enable running the SwitchProducer integration tests. This PR enables the tests.

Tested in CMSSW_10_5_X_2019-01-25-1100, no changes expected.

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)

the added unit test is correctly executed, and the compilation warnings appear to be unrelated to this PR
