Enable Profiler in WebApplicationFactory cause DI error

[xiaomi7732]

This is reported in #182. Since it looks like a different bug, I moved it here.

Basically, sloncho reported that Enabling Profiler in WebApplicationFactory scenario breaks the DI graph due to lack of process id.

Here's the attached callstack:

This is initially found on 2.5.0. I have a hunch that it is due to the fix of #140 and #167. I'll investigate.

Hi sloncho, thanks for reporting the error.
I can't reproduce the issue on my end. Need more info for troubleshooting. To help me understand the scenario, do you mind taking a look at this repository:

https://github.com/xiaomi7732/Profiler-WebApplicationFactory-tests-troubleshooting

and help me understand the difference between that project and yours and why there is no issue on my side.

Command logs FYI:

Since the process id, in this case, isn't critical to have, I have a workaround baked into the next release. ETA to ship with 2.5.1.

@sloncho, just so that you know, the workaround should have been released in this beta package:
https://www.nuget.org/packages/Microsoft.ApplicationInsights.Profiler.AspNetCore/2.5.1-beta2

Stable package released: https://www.nuget.org/packages/Microsoft.ApplicationInsights.Profiler.AspNetCore/2.5.1
