Make location.host and location.hostname return “” for host-less URIs

In the rather straightforward bug 562433, Firefox’s location.host and location.hostname need to return the empty string for host-less URIs instead of throwing an exception. What ends up wasting my time with such 1-minute fixes is figuring out the right test location and the right command to run the test. At least documenting this should save a few minutes next time:

See the Mochitest automated testing framework documentation for details.
