[Patch] Zoom to layer doesn't work well with GPX track containing waypoints far away

[GerdP]

What steps will reproduce the problem?

1. Load a gpx track containing waypoints far away from the track (in my case they mark my personel todo list)
2. Note that this creates two layers, one for the track, one for the waypoints
3. right click on the gpx track layer and select "Zoom to layer"

What is the expected result?

JOSM zooms to the area covered by the gox track

What happens instead?

JOSM zooms to the larger area covered by both waypoints and track.

Please provide any additional information below. Attach a screenshot if possible.

I think I get the same result as when I select the waypoints layer and "Zoom to layer".

Simple approach to fix the problem, works also for gpx files containing routes
