Suspending imported users with no recorded IP addresses lists most others as "same IP"

Hi there, little quirk I just discovered that might be considered a bug: When manually suspending a user that was imported from my previous forum engine and never logged in to the Discourse site, it suggests I also review 40,000 other users with the “same IP address”. Not a big deal, but it might be a good idea in that function to ignore users with a null access log.

When suspending users that have logged in to Discourse this doesn’t happen.
