Issue Description

Breakpoints based on Hit Count don't work when Set-StrictMode is set.

Expected Behaviour

I expected the Breakpoint to be hit.

Actual Behaviour

Breakpoint was not hit.

Here are my steps to reproduce the issue:

1. Started Windows Sandbox
2. Installed PowerShell: PowerShell-7.0.0-rc.2-win-x64.msi
3. Installed Pester: Install-Module pester -Scope CurrentUser
4. Installed VS Code: VSCodeUserSetup-x64-1.42.1.msi
5. Add the following to settings.json:

{
    "powershell.developer.featureFlags": [
        "PSReadLine"
    ],
    "editor.fontSize": 11,
    "terminal.integrated.fontSize": 11,
    "extensions.ignoreRecommendations": true,
    "extensions.autoCheckUpdates": false,
    "extensions.autoUpdate": false,
    "powershell.developer.editorServicesLogLevel": "Diagnostic",
    "powershell editor services.trace.server":"verbose"
}

6. Installed PowerShell extension: PowerShell-Preview-2020.2.0.vsix
7. Closed VS Code
8. Unzipped test project (Issue.zip) to a folder on the desktop
9. Right clicked on folder and selected Open with Code
10. Set a Breakpoint on line 4 of HitCountNotWorking.psm1
11. Edit Breakpoint: Hit Count = 1
12. Opened Test-HitCountNotWorking.Tests.ps1
13. Clicked Debug tests
14. Breakpoint was not hit
15. Opened HitCountNotWorking.psm1
16. Commented out line 1: # Set-StrictMode -Version Latest
17. Opened Test-HitCountNotWorking.Tests.ps1
18. Clicked Debug tests
19. Breakpoint was hit

The hit count relies on script that is not strict mode compliant, which is likely why you are hitting this issue. Because of this I will mark this as an enhancement, although we may investigate alternatives to this script. Thanks!
