Reset built model flag at presolve in nonlinear (#5386)
Fixes a bug in incremental with non-linear where the built model flag would still be true on the first call to check in a 2nd call to check-sat in incremental mode. This occurs when we are under the same SAT context when the model was built (likely level 0) on the subsequent check-sat call. Fixes #5372
