[relate] Partially fix Point-sized Linestrings support in relate(L/L).

Browse Source 
The latest robustness upgrade introduced changes that broke the support:
1. degenerated turns are now method_none+c/c. This is fixed by this commit.
2. ratios aren't calculated for degenerated turns (proviously distances were calculated by AssignPolicy).
