Prevent caching projections in the case of cycles
89164cd 
When normalizing a projection which results in a cycle, we would
cache the result of `project_type` without the nested obligations
(because they're not needed for inference). This would result in
the nested obligations only being handled once in fulfill, which
would avoid the cycle error.

Fixes rust-lang#79714, a regresion from rust-lang#79305 caused by the removal of
`get_paranoid_cache_value_obligation`.
