Fixed c_and_u tests a bit

Was getting all hung up on the fact that the page wasn't the right one....a result of some of our browser session foo.
Previously, the test assumed it would only receive an infrastructure vm, but as it only received the first VM from the database, it could (and has been for me) a cloud vm. The query has now been altered to
 a) only return vms which are from an Infrastructure provider
 b) ordered by name alphabetically so we don't have to go through pages and pages of vms to find it (I frequently got one starting with w or v)
