Steps to reproduce

We have an internal module, let's call it "TShell". It exports a command called "Open-Device".

If I run Get-Command Open-Device, then it will show me the command from the TShell module. If it hadn't been previously loaded, gcm triggered module auto-load, so TShell is always loaded afterward.

Hm, could I bypass this auto-load-during-query behavior? It seems like the -ListImported switch is exactly what I want--the documentation says it will "get only the commands in the current session."

But no: Get-Command Open-Device -ListImported still triggers TShell module auto-load.

(This also makes the -ListImported switch totally pointless: yeah, it only shows commands that are in the current session... but only because it already loaded them!)

Expected behavior

Don't trigger module auto-load when running `gcm -ListImported`.

Actual behavior

Modules get auto-loaded... so now the commands are imported (when they weren't before).
