Changing maximum results shown in settings doesn't take effect right away

[deefrawley]

Going to Settings and changing the "maximum results shown" doesn't take effect until Flow is restarted. I.e. changing from 5 to 10 still shows only 5 results in susbequernt queries. Restart Flow and 10 results per query show.

Flow Launcher version: 1.8.3
