Can "Restart build" to use latest .travis.yaml configuration

I updated .travis.yml and restarted job but it still use old configuration.
However, it uses latest code (by fetch +refs/pull/<pr-id>/merge:).
If it’s possible to use latest .travis.yaml, it will be very convenient.

Please try updating your PR to merge the changes to your .travis.yml.
