Bug: Cannot track current position

[varenius]

We can use "track" to track a galactic position, unless we are already at this position. To reproduce

1. Input galactic longitude = 140, latitude = 0 (always visible from Onsala)
2. Press "Track". If we are not yet at the postiion, telescope will start slewing and eventually reach target position. It will then keep tracking.
3. Stop tracking. Now, without changing the coordinates, quickly (before it moves 0.1 deg) press "Track" again. It instantly goes back to "Idle" and tracking is disabled. Expected behaviour is to track the position, even if already there.

I noted that: actually, after I uncheck "Track", while the telescope stays "Idle" and tracking box is unchecked, it does continue tracking! As long as the updated coordinates does not change 0.1 deg one cannot enable the tracking, but one the coordinates jump 0.1 deg, it will go back to "track" itself. A bit weird :).
