[FIX] stock: fix move line without state

When the "Show Detailed Operations" is enabled on a picking type,
create a immediate transfers with it, validate, unlock and readd
a new detailed operation, save and it will create a move line without
any state. Due this lack of state, the quant won't be updated.

Fix by remove the readonly=False in the state fields
(3f4f77fd), to avoid sending
state:False by the web client.
