Patch: Fix ref leak in folder list store get_parent_full_name

[José Dapena Paz <jdapena igalia com>]

	Hi,

	This patch avoids a reference leak on obtaining the parent full name.

Changelog entry:
* libtinymailui-gtk/tny-gtk-folder-list-store.c (get_parent_full_name):
  there was a reference leak in this method, as the recursion for
  getting the list of all parents was not properly freeing the
  objects.
