Second freeze exception request for Epiphany

[Michael Catanzaro <mcatanzaro gnome org>]

Hi release team,

When Epiphany's clear personal data dialog is used to clear saved
passwords, Epiphany deletes only passwords in gnome-keyring saved by
other applications, and never any of the passwords it saved itself. So
it's totally broken and quite destructive; hope you had another copy of
those passwords....

There is a small patch for this in [1] that it would be nice to land.
This has been broken forever so it's no regression if we leave it for
3.18.1, but it'd be nice to get it in.

Thanks,

Michael
