ocabot sometimes not merging some PRs

[nilshamerlinck]

In the last weeks, I noticed that the ocabot sometimes doesn't fully complete merge tasks, for no valid reason: i.e.

• despite pre-commit and travis checks being green on the merge branch, see for example https://github.com/OCA/field-service/pull/859
• not even creating the merge branch, and without any other explicit message error, see for example: https://github.com/OCA/intrastat-extrastat/pull/154

Trying again (eventually twice) is enough for the task to finally go through, see for example: https://github.com/OCA/bank-payment/pull/866

I'm not familiar enough with the ocabot code to make any hypothesis. Does somebody have an idea what could explain this irregular behavior?

This has happened due to GitHub expiring token due to a secret reveal. It should be fixed with #163.
