https://github.com/chaosbot/Chaos/pull/545: Fix "ci failed" issue v2

Description:
Previously, chaosbot would remove the tag when the build was still pending. That caused problems, as seen in #543. With this, it should be stable (it won't be removed then added again).

:white_check_mark: PR passed with a vote of 6 for and 0 against, a weighted total of 6.0 and a threshold of 6.0, and a current meritocracy review.
