Tweak the test commands in the Makefile.

Switch the test commands to be a little more user friendly in the Makefile.

`make unit` is now really fast with no reporting
`make integration` is slower

`make test` does it all with reporting

Might make sense to remove the reporting from `make integration` as well and just
have that run on `make test`
