Reduce RPC context
The server defines a few user fields to set as context but locale
is only used by the client so there is no need to put it back in each RPC and the .rec_name
are set for editing the preferences so they are neither needed in RPC.
The others like language_direction
, groups
or company_work_time
are not actually used but they could be if we need to make some rendering on the server side following the client configuration.
