Improve error message for Get-Service with an invalid ComputerName

Filed on UserVoice: http://windowsserver.uservoice.com/forums/301869/suggestions/17193962

The error message for Get-Service returns a NoServiceFoundForGivenName exception even when the problem is an invalid -ComputerName, potentially misleading the user.

Steps to reproduce

Get-Service wuauserv -ComputerName MadeUpComputerName

Expected behavior

Get-Service : Cannot find any computer with name 'MadeUpComputerName'.
At line:1 char:1
+ Get-Service wuauserv -ComputerName MadeUpComputerName
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (wuauserv:String) [Get-Service], ServiceCommandExce
   ption
    + FullyQualifiedErrorId : SomeOtherExceptionForComputerNameNotFound,Microsoft.PowerShell.Commands.GetService
   Command

Actual behavior

Get-Service : Cannot find any service with service name 'wuauserv'.
At line:1 char:1
+ Get-Service wuauserv -ComputerName MadeUpComputerName
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (wuauserv:String) [Get-Service], ServiceCommandExce

This issue should probably be closed since issue #5090 which has been addressed in pull-request #5094

Yes,it can. But on the other hand, adding the new exception we improve the error handling.
