patch 8.0.0649: when opening a help file the filetype is set several times

Browse Source 
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.
