Invoke-DcnRepairClone errors when PSDrive exists

[lowlydba]

Before submitting the bug

• Ensure you are able to reproduce it on the latest released version (we release often)
• Verified this bug is not already reported in an issue
• Verified errors are not related to permissions
• Can reproduce in a clean PowerShell session (clean = powershell -NoProfile)

Describe the bug
When running Invoke-DcnRepairClone, the section that validates the PSDrive errors out if the drive already exists since the New-PSDrive command doesn't gracefully handle existing drives. It should check for the drive before attempting to create it.

dbaclone/functions/clone/Invoke-DcnRepairClone.ps1

Lines 134 to 140 in a0bb715

	# Check if the parent of the clone can be reached
	try {
	$null = New-PSDrive -Name ImagePath -Root (Split-Path $image.ImageLocation) -Credential $Credential -PSProvider FileSystem
	}
	catch {
	Stop-PSFFunction -Message "Could not create drive for image path '$($image.ImageLocation)'" -ErrorRecord $_ -Continue
	}

To Reproduce

No more errors in my life 🎵
