As far as I can tell the vm tab doesn't get automatically updated via
javascript when the state of a vm changes, thus I need to wait a little
time and manually refresh the page before I check for the status. I
could do an assertion on the backend, and check the actual vm table
entry itself, but these are interface tests, thus assertions should be
on interface components.

Selenium raises an exception when wait_for_condition times out and the
test fails so the assertion can be safely removed. My bad on the
commenting, just code I forgot to remove, will keep it in mind in the
future.
