closes #975

@kangax sorry to bother again, but looks like after migration to travis-ci.com PR build jobs aren't working anymore (was working for .org, e.g. #1005)

I don't know which is easier/faster:

• adding PR to webhook settings
• removing Travis CI from Branch Protection requirements

But whichever way that allows me to merge any PRs would be greatly appreciated.

@kangax friendly ping since I can't merge any PRs until this is resolved...

@alexlamsl sorry, I was away. Any ideas on how I can fix this?

[alexlamsl]

Sorry for nagging - so what happens is that PR-triggered jobs seem to work for travis-ci.org but not travis-ci.com, even though branch builds are working fine.

So while it could be some settings not enabled on the Travis CI side, but failing to narrow that down just remove Travis CI from the branch protection criteria for now.

@alexlamsl what about now?

@kangax the merge button now works, thanks!
