Remove databases from laptop install script. (Shift3#33)

As we do 99% of our development inside of docker containers, installing
databases locally just ends up creating more conflicts then it solves
(such a port conflicts as such). Once a developer knows docker in and
out, and their system in and out, they will be able to manage multiple
installs just fine. However out of the box our expected flow is using
Docker.
