desktop: let tag-widget completion popup accept composition events

Browse source 
Attn: horrible hack!

For some reason the completion-popup does not have the
Qt::WA_InputMethodEnabled flag set. Thus, if the popup is open
composition of characters breaks.

Therefore, when starting completion, explicitly set the flag
on the popup.

This is 100% not how this was intended, but seems to work for
now.
