Remove spike rejection from gps filter (due to the tunnel problem)

[flonix8]

Description

• Remove spike rejection
  • The filter got stuck when entering a tunnel, because the next coordinate would trigger the spike rejection
  • This could be fixed with more logic, but we realistically don't really need it, because most GPS devices should filter out single spikes (according to a lot of data we've seen so far)
• Add test for this error mode

Motivation and Context
