Fix Windows tests

[jribbink]

Closes #1556

Description

Fixes our long-standing issue with Windows tests doing nothing :P. The CGO fixes we made a while back sovled half the issue, this solves the rest.

Example failing CI here (we used to have the issue that failing Windows tests didn't cause the to fail, this shows that it is fixed): https://github.com/onflow/flow-cli/actions/runs/8915898654/job/24486335666
