tdf#141217: Improve plain text pasting on iOS

Handle public.utf8-plain-text. That is the actual concrete UTI for
UTF-8 text. For instance if you copy text from the Safari address bar,
public.utf8-plain-text is the only type put on the pasteboard.
Previously we were not able to paste than into the iOS app at all.
