tdf#86731 Don't show 'spelling complete' when dictionary is missing

To check if dictionary is missing we have to run spelling which
checks used language for each text portion.
When AutoSpelling or manually invoked Spelling is performed SwDoc
receives notification about missing dictionaries. Then it is possible
to not show 'Completed' dialog.
