Add a Test-Path around the line which auto-imports modules into runspaces

[Badgerati]

Describe the Bug

When you have modules like Oh-My-Posh (OMP) installed, and you have Pode's auto-module importing enabled, you can run into issues because OMP will generate randomly name internal modules which don't actually exist. When Pode tries to import one of these, it fails and crashes out the starting of any runspaces.

Primarily, here:

Pode/src/Private/Helpers.ps1

Lines 937 to 942 in d26db35

	function Import-PodeModules {
	# import other modules in the session
	foreach ($path in $PodeContext.Server.Modules.Values) {
	$null = Import-Module $path -DisableNameChecking -Scope Global -ErrorAction Stop
	}
	}

Steps To Reproduce

1. Have Pode's auto-module importing enabled
2. Have OMP installed, and imported
3. Attempt to start any Pode server

Expected Behavior

The server should start successfully.

Platform

• OS: Windows
• Browser: N/A
• Versions:
  • Pode: 2.10.0
  • PowerShell: 7.4.2

The commit above also includes a fix for a stack overflow issue when converting $using: scoped variables, which was commonly seen when using Pode 2.10.0 with Pode.Web 0.8.3
