tests: Reorder Dockerfile statements to allow caching

Browse Source 
Docker creates intermediate layers on each command (for most commands),
but the COPY was invalidating them too early, every time it runs it was
generating a different layer.

This patch moves the COPY down to the bottom, and adds a bit more
organization to the commands below.
