Search function shows results if nothing was found

[Fry-kun]

Describe the bug Search function in Afwall+ app behaves unexpectedly: When I enter a letter which should show no results, the previously shown results are still shown. For instance, if I search for "xx" the only result is "Nexx" app (correct result) -- but any further letters keep showing the same thing. This is confusing behavior; there should be some indication of "no results matched", instead.
