lok: make sure flushPendingLOKInvalidateTiles() is called

SwViewShellImp::AddPendingLOKInvalidation() collects invalidations,
but this was relying on something eventually calling
flushPendingLOKInvalidateTiles(), which wasn't guaranteed.
If e.g. a spellchecker caused an invalidation from in idle callback
and nothing else changed, then the LOK callback handling code
didn't know there was something pending. So add an explicit
call to ensure to notify about these pending invalidations.
