Install qiskit in ci env

This commit ensures that we're actually installing qiskit in the travis
environment. Previously we were just running tests out of the qiskit
repo without installing it. This made things like testing jupyter or
external commands more difficult because we had to properly setup the
path to make sure the qiskit code was discoverable. This fixes that by
installing qiskit (in develop mode) so that the code is linked to the
python site-packages and is discoverable/importable by other python
packages on the system, regardless of where they're run from. This is
just a stopgap patch until we switch to using tox for ci, which will do
this for us as well.
