Cannot extract archives if a variable named srcStream exists

[bematteo]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Steps to reproduce

I had a string variable named $srcStream declared before calling Expand-Archive, because of that I was getting this error:

Method invocation failed because [System.String] does not contain a method named 'Dispose'.

The problematic code is in Microsoft.PowerShell.Archive.psm1, where $srcStream gets disposed.

To reproduce:

$srcStream = "whatever"
Expand-Archive -Path "arc.zip"

Expected behavior

Archive gets extracted

Actual behavior

Extraction fails
