gnome-text-editor: only handle spellcheck language if needed

The Flatpak build doesn't have the spellcheck issue at the
moment, and it may be fixed soon in the RPM build. Trying to
'fix' the issue on the flatpak build actually makes the test
fail. So, let's only do the fix if we actually have a misspelled
word.
