Update username & password data for Location (#5925)
Update username & password data for Location (#5925)

Location doesn't expose password and username members in any current browsers,
and there are no such members in the current spec for Location:

https://bugzilla.mozilla.org/show_bug.cgi?id=1213815

Firefox between versions 26 and 45 did expose username and password
members for Location, but apparently no other browsers ever did.

Relevant Firefox bugs:

* https://bugzilla.mozilla.org/show_bug.cgi?id=887364 (Firefox 26 addition)
* https://bugzilla.mozilla.org/show_bug.cgi?id=1213815 (Firefox 45 removal)
