Issue Description

I am experiencing a problem with running Pester test inside the editor.
The name of my test use simple quotes :

Describe 'Exported variable $IsoCountiesFR'

But during the invocation -TestName use double quotes :

Invoke-Pester -Script "g:\PS\FluentDateTime\Test\Get-PublicHolidayFR.Tests.ps1" -TestName "Exported variable $IsoCountiesFR"

This expand the variable and change the name of the test that do not exist

Good catch! I'll get it fixed.
