[geary] Remove ComposerWidget.ComposerState.NEW enum value.

[Michael Gratton <mjog src gnome org>]

commit 1aa91639b1f36c0b2023f9b2df93ad8cab5604ea
Author: Michael James Gratton <mike vee net>
Date:   Wed Feb 7 11:16:30 2018 +1100

    Remove ComposerWidget.ComposerState.NEW enum value.
    
    * src/client/composer/composer-widget.vala (ComposerState): Remove NEW
      since it doesn't actually describe a useful state and effectively is a
      duplicate of PANED.
