EliteDangerous: fixed Route details event

Now not firing on atuomated events like handing in missions which caused
an event of type `update`. Might need additional tinkering in the future
if I want to expand on the functionality, like actually having voice
commands for mission route updates. I don’t see that coming, but who
knows.

fixes #46
