Clicking 'debug test' twice runs two instances of the debugger simultaneously

[willfaught]

Reproduce:

1. Set a breakpoint.
2. Click 'debug test' and wait to hit the breakpoint.
3. Step one line forward.
4. Click 'debug test' and wait to hit the breakpoint, again.

Thanks for reporting @willfaught

The apis available to track a debug session can be found at https://github.com/Microsoft/vscode/blob/1.18.1/src/vs/vscode.d.ts#L6112-L6134 which can be used to disable the debug code lens when a debug session is already active.

The codelens for the tests are created in https://github.com/Microsoft/vscode-go/blob/0.6.69/src/goRunTestCodelens.ts

PRs to fix this issue are welcome.

I can no loger reproduce this since version 0.6.76+, vs code 1.20.1 commit f88bbf9137d24d36d968ea6b2911786bfe103002

PS: I did not test it yet on bigger projects, only with github.com/go-training/helloworld, but it looks promising since I recall having this issue before

Could someone else try to reproduce it?

On Windows I get an error when trying to debug the second time

go install testmain: open c:\GoCode\src\github.com\golang\example\stringutil\debug.test: The process cannot access the file because it is being used by another process.
Process exiting with code: 1

But I do see it on my Mac

I used the https://github.com/golang/example/stringutil project
