CORE-14306
Yes, it checks the input handle and doesn't fail if an invalid level is given, because someone may still send a Command.
This also fixes CORE-12794. Thanks for reporting!
* Pass the correct handle to _RpcGetPrinter in GetPrinterW.
* Pass an empty string instead of a NULL pointer as wszComputerName to the GetPrinterLevel* functions, because this variable is later used as source for StringCbCopyExW.
* Don't check for GetLastError() == ERROR_SUCCESS in tests. Windows apparently only sets the last error in case of failure.
The Printing code should probably be changed similarly in a future commit.
Should fix CORE-14072
