Slack Gardener tries to archive a channel that has been unarchived

[njmoorewitchcat]

Description

When you un-archive a channel, the next time the gardener runs, it wants to re-archive the channel. It probably should take into account the un-archive time as part of the post history for counting.

Steps to Reproduce

1. Let gardener archive a channel (then you know you have reached the sleep time)
2. Unarchive the channel
3. Wait for the next run and it wants to archive the channel you just unarchived.

Expected behavior: It doesn't ask to archive a channel you have just unarchvied until much later.

Actual behavior: It wants to archive a channel I have just recovered.

Reproduces how often: I guess every time.

Thanks for submitting an issue @njmoorewitchcat, have you found that it warns the channel again? or just archives the freshly unarchived channel when the gardener next runs?
