Wrong order of first and lastname

[Johannes Kempf]

If you swap first and lastname of a contact; the message view isn't updated properly.

Steps to reproduce:
a) Create a contact with swapped naming, e.g. write "Firstname" in the field for lastname and "Lastname" in the field of firstname.
b) Write a message to this contact.
c) Note that the messaging app displays "Lastname Firstname" as full name in both views: List of messages and Chat details; see attached image 1) and 2)
d) Change the order in the contact in order to correct the naming, e.g. write "Lastname" in the field of lastname and "Firstname" in the field of firstname.
e) Note that now the list of message displays the correct full name "Firstname Lastname" 3) whereas the chat view still displays the wrong ordering "Lastname Firstname".
