Receiving SMS via libmm functions doesn't work anymore

With the '85a2386f purism/sloppy' build the reception of SMS doesn't work at all anymore in Chatty, because the SMS pdu-state isn't provided, even though a related patch has been committed: https://source.puri.sm/Librem5/ModemManager/commit/6068a4460c6d46a8dd02de47035303248ee3497a

When testing with a MM build from master, which includes this patch as well, everything works as expected: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/commit/0c921bbc94b466464b97f33d7f54c64c768402eb

For testing run Chatty with the libpurple-mm-sms plugin. When the patch for the SMS properties-initialization is applied correctly, Chatty should be able to receive SMS > 160 characters.
