search is broken sometimes

### What Happened?

Every once in a while, usually after a few days of usage, the search in Slingshot breaks. I try to search something, but it shows matches for some older search and it gets impossible to search anything else.

Here is one screenshot demonstrating it:


### Steps to Reproduce

I'm really not sure what are the preconditions for this. But I think it usually happens after a few days of uptime. The steps are then:

1. Open app menu (with Super+Space or a click at the wingpanel button)
2. Type to search
3. The results and matched parts are different then what I typed. They always correspond to some older search.

Repeating with different search terms shows the same old results.

### Expected Behavior

Obviously it should show search results for what I type.
