Previous approach for printing report was using temporary fields in ifrs.line model
which was causing that only one user was allowed to print one report at a time.
New approach uses ModelTransient, osv_memory, model as temporary records,
as each wizard creates a new record and with it twin lines for report are created
and in this twin lines temporary fields are written avoiding concurrence errors.
