Fixes protection for scooping tropical fish.

https://github.com/BentoBoxWorld/bentobox/issues/349

Also added pagination to protection flags and localized alphabetical
sorting of the flags.

Also added defensive code should a flag enum be removed but it is still
in the island database. In this case it will just be ignored and at the
next database object save it will disappear.
