Temp: Add commands to clear out left-over secrets in CI build

[stuartleeks]

Temporary PR to have a build that clears out secrets left over from previous test runs to workaround errors such as found in this build

My assumption is that this will be rendered unnecessary by #101 at some point?

Closing as I don't believe this is needed now that #101 is merged
