[Code Cleanup] Resharper Warnings (#2235)

* Remove unused local variable

* Remove another unused variable

* Correct typos and remove unused initialization

* Cleanup some code in OPCharCreate

* Remove unused function in client.cpp and undefined declaration.
Also the function potentially had a null pointer dereference according to Visual Studio.
