[fix] remove destructor in mutex

[skalenji]

Mutex destructor is used to as a fail safe to release locks in case process is terminated unexpectedly, this is not really needed and could lead to errors
* The actual lock provider responsible for releasing the lock could be destructed before the mutex, during shutdown there is no guarantee in order of which objects are destructed
* All lock providers extend the LockAbstaract class which already has a destructor responsible for freeing locks in case of failure
* Throwig exception in the destructor is not a good idea, doing so triggers a fatal error

@arvenil can you check this please?

@skalenji You need to remove the destructor on NinjaMutex\Lock\LockAbstract too.
