Continue running network tests after failure (#26407)

Previously tests would stop running on the first failure.
With this PR we move onto running the tests for the next module. This
allows DCI runs to have a fuller picture of what's broken.

This only effects manual and DCI runs, it doesn't effect Shippable runs
as this the modules are tested directly.
