Invoke-git not working when given a network Path

[JefeDavis]

Resolve-Path is prepending is prepending the powershell provider to the name for the path property, that's usually what you get when in the PsPath property.

System.Diagnostices.ProcessStartInfo Objests do not support the prepended powershell provider for working directory, consider switching the following line on Invoke-git.ps1 line 83

$Path = (Resolve-Path $Path).Path
to
$Path = (Resolve-Path $Path).ProviderPath
