[FIX] web: update renderer when _callButtonAction failed

Before this rev., the following scenario didn't work:

Open manufacturing order and click on Produce button (note that
bom product should have Serial number enabled) then add quantity
in Done field in o2m and press Record Production button in wizard,
it will produce UserError and after then if you change Lot number
field in wizard's o2m then the many2one value doesn't get selected.

This occured because the renderer wasn't updated after the RPC fail
and thus still got an outdated version of the state.

The issue raised after commit: 02eef78bbd3 which was done to remove
useless rpc call, it's OK to remove rpc call but let's keep
updating renderer.
