fix(MaintTest): quickfix of ci timeout issues

[nharrand]

This should fix timout issues on travis. It is only a quick fix that print and flush() a message after each package testing for the one test that takes a long time.

The offending test is MainTest#testElementToPathToElementEquivalency() and we might want to rework it. (Keeping in mind that we should not blame whoever wrote it... 😇)

I suggest that we select a meaningful subset of the sources on which it runs. (So far it runs on the complete spoon AST).

Thanks a lot.

LGTM. Will merge it.

Yes! Let's do this in a separate PR. Could you open an issue to keep track of it?

[nharrand]

Done!

seems like he quickfix is not enough: https://travis-ci.org/INRIA/spoon/jobs/441787940

That's really weird because the output I just added is indeed printed... Was it the wrong print stream? Well anyway I'll try to reduce the duration of the test overall.
