Hi,

I was inspecting failures in stable triggered by (test) dependency
changes and noticed that the test fails on:
767s E           lava_common.exceptions.InfrastructureError: Unable to
fetch git repository 'https://git.linaro.org/lava-team/refactoring.git'

While it's a quite annoying that tests start to fail when external
resources become unavailable, the test also misses the needs-internet
restriction to clearly annotate that resources from the internet are
required for the test.

Please add the restriction for tests that use external resources.

Paul
