lok: don't render active textbox on all slides

when we render tiles for slide previews we use
viewid = 0 (first session)

so when first session edits any textbox and in other
session we request slide previews (eg. after new slide was added)
then we received tile with additional text from the first session

this is caused by:
commit bee4ff508a456a1552aacdf6fc838b8b7cffb9ec
desktop lok: avoid unnecessary setPart() in paintPartTile()

If possible, switch views, not parts, that way started Impress text
edits don't end as a side-effect.

but later there was a fix which doesn't trigger closing of texbox
editing when switching parts:

commit ce7bf351972bbfd64ca99e8d2fb4c5f77591c9e0
impress: don't exit textbox editing when new slide was added

so we don't need that in all cases...
to fix issue described above: still switch views instead of parts
when possible - but avoid views where editing is active
