[FIX] web: o2m list with field datetime from server

Have the create_date field displays on a one2many list
Try to add a record onto the list

Before this commit, when the virtual record is added onto the list
it crashes because the datetime field is undefined and cannot be parsed

After this commit, It doesn't crash though the value would have to wait the save on the main record
to be updated (because it is the create_date)
