[notifications-tests] Added very basic tests of Notification instance. (#1625)

Some browsers still haven't moved DOM attributes to prototype chains, so we
still can't properly test interface conformance in those using idlharness.

Thus the assertions in this file provide very basic tests of all the attributes
the spec requires Notification instances to expose, so we can at least have a
means for examining browser support for the Web Notifications spec at that
basic level in all browsers, even if ones that don't conform to WebIDL.
