patch 8.0.0649: when opening a help file the filetype is set several times
Problem: When opening a help file the filetype is set several times.
Solution: When setting the filetype to the same value from a modeline, don't
trigger FileType autocommands. Don't set the filetype to "help"
when it's already set correctly.
