fix: [#2473] ignore 0 sized precollisions (#2474) master

Closes #2473 This PR fixes an issue where a degenerate 0 sized collision causes issues with the precollision event emit. Previously an erroneous left precollision would be emitted when the minimum translation vector (mtv) was `(-0, -0)` <img width="299" alt="image" src="https://user-images.githubusercontent.com/612071/187574499-96889716-ba1a-418e-995e-b7673ce643e2.png"> ## Changes: - Filters out 0 sized contacts in precollision to guard against a degenerate side calculation
