Doesn't properly remove labels

[mxstbr]

Repro:

1. Tick "WIP"
2. Do some work
3. Edit comment to untick "WIP" and tick "Ready for Review"
4. The bot doesn't remove the old label

I believe this bug comes from this line in uncheckedLabels reducer

    return [...labels, label]

the expected result of the repro for the code to work the "WIP" checkbox should match the label exactly, otherwise, the filter of current labels will not find the "WIP: Building"

Shouldn't it be rules.label instead?

Edit 1: worked just fine in my tests just now, so no clue no more, lol
maybe close the issue?
