Move to Travis GitHub app with checks

[gene1wood]

Can we change our travis integration to use github apps and checks?

@hidde any objectsion? I'm happy to switch us over

That's a great idea.

The announcement does say:

Open source projects on Travis CI will soon have the option to migrate over to travis-ci.com. We’ll do a wider announcement when this is ready.

So, not sure if we can move to it yet?

Thanks for switching us over!

Ok, I've deleted the Travis CI Service (not GitHub App) from the mozilla/auth0-custom-lock integrations & services page.

It looks like Travis CI is already setup as a GitHub app (I think). I'm not entirely sure. I guess if the next merge results in a build then we know its working.

There’s now a semi‑open beta for the migration to Travis‑CI.com: https://docs.travis-ci.com/user/migrate/open-source-repository-migration (requires opt‑in via email)
