As seen in the screenshot below, aircraft trails in SkyView sometimes have gaps when an estimated segment ends.
This PR fixes that problem and makes the updateTrack function consistent/logical and hopefully easier to understand.
After the change only the previous position is appended following the logic of that function, the current position is drawn only with the elastic band feature.
The number of line segments in memory is significantly reduced by both commits, this improves responiveness when using the "Show All Tracks" function.
