dynare_solve.m: return with valid solution even if Jacobian is ill-behaved

In pathological cases, the Jacobian at the initial but true steady state value is ill-behaved. In this case we should return with the valid steady state instead of trying random starting values

changed milestone to %4.6

added bug label

Doesn't this invalidate the fix for #1668 (closed)?

Compare with previous version

@sebastien Good point. I moved the check to only not do a Newton iteration if the Jacobian shows problems. That seems like a good compromise.
