Feature Request LoadBindingOverridesFromJson should discard invalid bindings

Currently we are saving player binding overrides using
SaveBindingOverridesAsJson()/
LoadBindingOverridesFromJson(). We recently updated and removed an old action. This causes LoadBindingOverridesFromJson to throw an exception if an override to this old action was saved. This seems to cause a corruption to the action bindings as most controls become broken. I can work around this issue with a try/catch and reset any overrides if there is an exception but it would be much nicer if I didn't have to throw out all of a player's saved bindings if we decide to change the action layout.
