Ray tracing solution appears twice

[cg-laser]

In rare cases both the direct and reflected solution are returned for almost the same ray. Receive angles differ by a fraction of a degree

In [9]: sim_station.get_electric_fields()[0][efp.ray_path_type]
Out[9]: 'direct'

In [10]: sim_station.get_electric_fields()[1][efp.ray_path_type]
Out[10]: 'reflected'

This must be a bug as the direct solution should originate from below.
