[review] Initialize common SMS fields early for multipart messages

[Aleksander Morgado]

Hey,

Until now, most of the SMS properties of a multipart SMS object were
being initialized once the SMS was fully assembled (i.e. when
absolutely all parts were received). This MR updates that logic so
that the common SMS object fields (e.g. pdu-type, number, smsc...) are
initialized as soon as the first part is received:
