Hardcoded -register:user parameter causes that when running Visual Studio as administrator OpenCover is not able to register profiler.

I have checked that with powershell runned as administraror I am unable to run OpenCover with -register:user but if I run powershell as normal user then it is fine

I think that would be great to add option to specify desired user. I am guessing that AxoCover stopped working for me after last Windows 10 update (1903)
