Sanitize negative followers count on APContact

Browse source 
Please see
https://github.com/friendica/friendica/issues/9498#issuecomment-818894106
and related discussion regarding this - it appears it's possible for AP
users, maybe just Mastodon users, to have a negative followers count.
This causes fatal errors in Friendica, so I think we should sanitize
this input.
