[geary/mjog/composer-autocomplete-fixes: 2/4] Don't use public addresses setter internally in EmailEntry

[Michael Gratton <mjog src gnome org>]

    Don't use public addresses setter internally in EmailEntry
    
    Fixes being unable to enter spaces or other punctuation in half-formed
    email addresses because the public setter was causing the entry's text
    to be reset with the formatted address.
