fix(migrations): Fix broken org to group search migration

[BYK]

This should fix getsentry/self-hosted#3766. That said it will cause data loss for the people who encountered the error as it will skip over the searches without an id. Not sure if this is the best approach as I'm not familiar with the issue.

@markstory if you need access to our instance (which was upgraded/migrated manually as described in the issue) for some reason, I can give you access to our server.

Looking at that sentry_groupsearchview table I can see, that the 2nd entry doesn't have a user_id or organisation_id - which seems to be the main problem.

I can see it in the UI as well, I am just confused, that it appears in the Recommended Searches part

The top 3 saved searches have been added today and they work fine.

Given the state of the schema when this migration would run, I think this is a reasonable solution. Searches that are lacking an owner_id will not be copied into groupsearchview, and will be lost in the future, when the UI switches over to groupsearch view completely.

Sorry just wanted to block in case this PR was missed: #93944

There is a followup migration added that checks for the missing owner ID, so we should just skip this one entirely

Closing in favor of #93944
