Fix: pwsh errors with "command not found"

[JustinGrote]

pwsh includes the -login switch which causes the split to not work correctly. This fixes that issue.

I don't think we will merge this, I want to regress the -login/-l thing.

[JustinGrote]

@catthehacker no prob, would you like a separate PR to remove the login switch?

[catthehacker]

Currently I don't want to touch most of the codebase until other PRs get merged since there are few quite important fixes that should be in master first (643, 566, 635, 648...).
I want to see where we are after all that.

@brian-pickens why? This PR is no longer needed

[brian-pickens]

I misunderstood the purpose of the PR initially, trying to troubleshoot my own issue. I'm thinking I need to use a more fully featured image to get access to powershell.
