If no package is uninstalled the cmdlet should emit an error

[SydneyhSmith]

Summary of the new feature / enhancement

If no package is uninstalled during a run of Uninstall-PSResource the cmdlet should emit a warning so that the user knows no action was completed. The warning can suggest users run Get-PSResource.

Alternatively this message could only be included in runs with -Verbose parameter

Proposed technical implementation details (optional)

I just ran into this and it should really return a non-terminating error for the caller to know something didn't work as expected.

Here is my example, by trying to uninstall a specific version of PSReadLine it gave me every indication that it worked as expected.

PS C:\> Get-PSResource -Name PSReadLine
