Could you please cleanup ios/chrome/browser/sessions/DEPS from exceptions and
add crbug.com/619992 to BUG= line.

Done.

Should we use CRWNavigationItemStorage key instead?

[kkhorimoto, 2017/02/03 00:36:09]

The unarchiver already knows to use CRWNavigationItemStorage's |-initWithCoder:|
when it attempts to deserialize objects with that class name.  This is just
added for backward compatibility so that if the unarchiver sees a serialized
CRWSessionEntry, it knows to use CRWNavigationItemStorage.
