fix dependency pip install with git, was missing -e (test still erring out locally and on travis, but closer)

* This will have wafflehaus and neutron dependencies install from git correctly:

   was installing wafflehaus like:

   `wafflehaus==0.2dev` 
   (which is master branch)

   and now will be:

   `-e git+https://github.com/roaet/wafflehaus.git@362a751d3733151f7a52404939d4bc70810dbbee#egg=
wafflehaus-origin/development` 
(which is the development branch)
* removed --upgrade from .travis.yml, did not help
* changed the coverage report folder to match what was in .gitignore
