tdf#142478 fix crash when searching and a viewshell change occurs

When searching a impress document for a word, and the word is in
notes as welll as in the document, a crash happens (only when
searching with "find all"). The regressing commit changed that the
search is now bound to a view (and to a viewshell). When searching
for words in notes and document, at the transition from "standard"
to "notes" page kind mode, the view and viewshells are destroyed
and the new one created again. The problem lies here as when we
destroy the viewshell, we also destroy the search context and
FuSearch objects, but we are still executing the search -> crash.

The solution for this is that when we change the page kind,
we take the FuSearch object from the old viewshell and put it
into the newly created viewshell, so that we keep the FuSearch
object alive and don't throw away the search context too.
