fix(storeFreeze): remove double error log
fix(storeFreeze): remove double error log

This fixes a problem where any error inside a reducer will lead to the `State mutation` message, even when that's not the case. Default error reporting already prints an error message to console with the actual error. 

Also, state mutation can also happen outside reducers (selectors, etc, subscribers, etc), so there's no point in handling this case as special.
