x/build/cmd/gerritbot: too many comments on a new pull request

[mvdan]

For example: #24322

I would expect two comments - "This PR has been imported to Gerrit", and the forward of the "Congratulations on opening your first change" automated comment.

However, somehow gerritbot (or perhaps GitHub?) seem to think that the pull request needed importing twice, or that it was updated when it doesn't look like it was.

Or perhaps the pull request was updated while gerritbot was importing it, resulting in these duplicate and confusing messages.

You say "for example" but has this happened on other PRs as well?

Not that I have noticed, but I haven't gone through all of them. I have only seen it once, so it's likely not something that happens often
