Patch: set proper locks on tny_gtk_header_list_model_set_show_latest

[José Dapena Paz <jdapena igalia com>]

	Hi,

	This patch adds proper locks on set_show_latest, to avoid problems of
concurrency if one thread is adding items to the model while another
thread changes the set_show_latest status.

	Changelog entry:
	* libtinymailui-gtk/tny-gtk-header-list-model.c: add proper
	locks on set_show_latest method to avoid concurrency problems.
