Title: Graceful istests

This is a first attempt at getting the istests to return False if the object is not even a Qobj. As mentioned in #2, there is a cyclical import if one check for Qobj in istests.py, because qobj.py imports from istests.py.

Since I changed quite a few things, you might want to have a closer look.
