Invoke-DbaDbClone tries to clone all databases instead of just one

[nvarscar]

Before submitting a bug report:

• 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)
• If issue is with Copy-DbaDatabase, using Backup-DbaDatabase | Restore-DbaDatabase still does not work

Note that we do not have the resources to make Copy-DbaDatabase work in every environment. Instead, we try to ensure Backup & Restore work in your enviornment.

Steps to Reproduce

Invoke-DbaDbClone -SqlInstance 'localhost' -Database 'AdventureWorksLT2012' -CloneDatabase 'AdventureWorksLT2012_clone'

Expected Behavior

Clone one database
