There are two bugs when using `/load <model>` for a model that doesn't exist, namely:
  1. it will not restore the current model settings if the current model is a thinking model; and
  2. it will crash is the current model is a non-thinking model

This bug fix saves the current runOptions and then restores them if the model load
doesn't happen. It also fixes the crash happening for non-thinking models.
