Restore the semantics of TrustRegionMinimizer

A previous change to fix a bug related to how x_norm was being
initialized changed the semantics of the TrustRegionMinimizer
loop. With the bug, the parameter_tolerance was being ignored
till the first successful step was encountered.

parameter_tolerance based convergence is a hack anyways, so
restoring the previous semantics is reasonable and will preserve
existing code/tests that depend on this behaviour.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.
