Patch: add camel folder reasons to sentbox and outbox while send queue is processed

[José Dapena Paz <jdapena igalia com>]

	Hi,

	This patch adds the tny camel folder reasons to the sentbox and outbox
while the send queue is processed, as we may have the reason counter get
to 0 on the send process (and then get crashes because of this).

	The changelog entry would be:

* libtinymail-camel/tny-camel-send-queue.c:
        * Add camel folder reason to sentbox and outbox while sending,
          as we can get unreasons and have then crash because the
          message cache is freed.
