Before this was calling `t.Log` for every read from the log file.
What we really want is to to call `t.Log` for every line since a `Read`
may return a partial line which will look weird in the output and be
difficult to read.

This also changes things to always write the build logs to the test log
instead of just on failure so its easier to see what's happening even on
a successful test run.

This prevents the skew of test times due to having to build the frontend
and worker images.

This makes sure we use the same cache keys for both the main Dockerfile
and the test fixtures so that we can avoid needing to pull down a bunch
of dependencies that we've already pulled down before.
