[evolution-patches] 42721, upgrading passwords 1.2 -> 1.3

[Not Zed <notzed ximian com>]

This should upgrade passwords for 1.2 -> 1.3, not sure if versions prior
to 1.2 stored them the same way.

Only tested for mail passwords, but so long as the component key has
remained the same, it should work for other components too.
