[low-priority?] Don't open an app if the search string is absolute gibberish

[1seco]

The search string ";slkdfpmerfmwpiueroijldfjknsldfmms;lkndf;gjl" opens system settings. It is a bit of a hilarious case, but maybe an option to not open any app if the search string is absolutely gibberish would be really 👌. I have absolutely no idea how this would be done, so it's just a suggestion.

Should be an easy fix. I guess the problem is just that the last match in the fuzzy search isn’t cleared when no matches are found. Would gladly accept a PR.
