[Bug] \Piwik\Archive\ArchiveInvalidator::removeInvalidationsSafely says idSites can be int, but that's not completely accurate

[snake14]

What happened?

I noticed that custom reports were archiving even after being deleted. Debugging, I ended up finding that if a single site ID is passed as the idSites argument, the removeInvalidationsFromDistributedList method doesn't handle it properly because of a TypeError on line 690.

What should happen?

Since the comment block says that int is an allowed type for idSites, the removeInvalidationsFromDistributedList should handle that as well, or the removeInvalidationsSafely method should wrap it with an array before passing isSites on to removeInvalidationsFromDistributedList.

How can this be reproduced?

Using CustomReports 5.0.17 or earlier do the following:

• Create a new report
• Note that the option record named ReArchiveList was updated to add the newly created report
• Delete the newly created report
• Note that the option record named ReArchiveList was not updated
• Note that archiving is done for the deleted report the next time archiving runs
