[Compatible] Use the archive URL for the current branch when running tests

[mrmr1993]

A change to the archive node schema on develop has broken the archive node integration tests on compatible. This PR is a reduced version of the fix applied to develop, which uses the github URL for the current commit instead.

Presumably we will require an equivalent fix on master.
