(In [8336]) AnnouncerPlugin: (i18n) Change msgid and update catalogs, closes #7251.

Remove a superfluous line introduced in changeset [8084] for unknown reasons while already doing changes in user preferences.

I've done minor editorial changes to the test while being there. Please comment, if you feel that current wording is not appropriate.
