Invoke-SqlDscQuery: InstanceName always set to default value in should process messages

[johlju]

When the command is called using the parameter set ByServerObject the parameter InstanceName is always set to the default value because $InstanceName is not changed according to the passed ServerObject.

SqlServerDsc/source/Public/Invoke-SqlDscQuery.ps1

Lines 187 to 188 in 3e81805

	$verboseDescriptionMessage = $script:localizedData.Query_Invoke_ShouldProcessVerboseDescription -f $InstanceName
	$verboseWarningMessage = $script:localizedData.Query_Invoke_ShouldProcessVerboseWarning -f $InstanceName

Suggest adding the following in the begin-block.

if ($PSCmdlet.ParameterSetName -eq 'ByServerObject')
{
    $InstanceName = $ServerObject.InstanceName
}
