[evolution-patches] Don't use weak references to clean up "const" values in EContact

[Ross Burton <ross burtonini com>]

Hi,

From http://bugzilla.gnome.org/show_bug.cgi?id=363445

Weak references are not free and EContact creates a new weak reference
for every time e_contact_get_const() returns a new value to clean it up
when the object dies.  This is a rather heavyweight way of doing the
cleanup, as it can be done fine in finalise.

The bug has a patch.

Ross
