#2206 Launcher: clear list of recently used locations

[Daniel Meissner]

On the forum it was reported, that starting a tutorial on the default c172 twice crashes the sim. This was on FG from Ubuntu 2019.1.1. See forum thread: https://forum.flightgear.org/viewtopic.php?f=20&t=37233

I can replicate this on next, but for me the c172 crashes the sim immediatly when starting the preflight tutorial. Crashlog:

Please close this one - form autofill, the desktop version of autocorrect :-/

Hehe, I was pretty confused by this one :)
