Travis: fix the build

[jrfnl]

The Travis docs say that $TRAVIS_BUILD_STAGE_NAME is in "proper case" form:

TRAVIS_BUILD_STAGE_NAME: The build stage in capitalized form, e.g. Test or Deploy. If a build does not use build stages, this variable is empty ("").

However, it looks like they made an (undocumented) change (probably a bug in their script handling) which means that the $TRAVIS_BUILD_STAGE_NAME name is now in the case as given, which in this case is lowercase.

This means that some of the comparisons are failing and the wrong things are executed for certain builds.

As I expect this to be a bug in Travis, I'm not changing the case for the comparisons at this time. Instead I'm fixing this by inline fixing the case of the variable for the comparisons.

Darn, sorry, didn't mean to close this.

I just noticed the build wasn't reporting back. I've restarted the build now, :crossed_fingers: that it will report back correctly now.

Grr.. build passes (again), but still not reporting back. Going to try a force push now.

@dingo-d Something seems to be wrong with the Travis reporting back. Shall I close this PR and open a new one for the same to see if that fixes it ?

[dingo-d]

Sure open a new one 👍 Thanks!
