lok sd: Fix crash when searching.

This is a follow-up of ed5450f2a5ed8e72b48b4d976217746cea04a5c9 where the
check for the HasView has been removed.  Turns out that there are conditions
when this really can happen, leading to crashes in the LOK searching.

Unfortunately I did not manage to find a reliable reproducer to create a
unit test :-( - so I suspect this commit might be more a workaround than a
root cause fix.  Would be great to find out the exact conditions leading to
the situation when the EditEngine does not contain the EditView, and evaluate
this fix against that - but that's hard without a reliable reproducer.

A unit test for this fix is missing from the same reason.  The unit test from
ed5450f2a5ed8e72b48b4d976217746cea04a5c9 still passes.
