Problem description

In Invoke-RestMethod, the PassThru parameter must be used with the OutFile parameter. The intent is that you can write the results to the file and get the output to the pipeline. But the cmdlets only write to the pipeline, not the file.

The problem code starts here:

if (ShouldWriteToPipeline)
{
   ...
}
else if (ShouldSaveToOutFile)
{
   ...
}

Notice that the logic outputs pipeline and skips the output to the file. Both ShouldWriteToPipeline and ShouldSaveToOutFile can be true so need to remove the else.

Steps to reproduce

Invoke-RestMethod https://taxonomyservice.azurefd.net/taxonomies/product-uri -PassThru -OutFile C:\temp\irm.json

Expected behavior

Output to console and to the file.

Actual behavior

Output to console only. The output file is not created.

Environment data

This affects all versions 5.1 and higher.
