[9.1.6] Name display order pref not take into account in Processing ticket

[nqb]

Hello,

In GLPI 9.1.4, when a user has "Name display order" preference set as "First name, Surname", this preference is not take into account only in Processing ticket tab if :

• user is the requester
• user adds a followup
• user adds a task

Steps to reproduce :

• Set "Name display order" preference set as "First name, Surname" for user Richard Stallman
• Create a ticket with requester as user Richard Stallman
• Save ticket
• Create followup as user Richard Stallman
• Create task as user Richard Stallman

In Processing ticket tab, you can see that :

• Requester name is in the form Stallman Richard
• Writer of followup and task is in the form Stallman Richard

However, in Ticket tab, all is right.
