RFR: 248: Only post integration messages to RFR threads once

[Robin Westberg]

Hi all,

Please review this change that ensures that `[Integrated]` messages are only posted to an RFR thread once, even if the commit is merged to another branch that is also watched by the notifier.

Best regards,
Robin
