[FIX] stock, stock_account: add move when picking is available

When a picking is available, any added stock move should directly be in
the available state. This is done thanks to a key in context put in the
one2many (stock.move) field on the picking view and an override of
stock.move's default_get. Sadly, an extension of the picking view in
stock_account redefined the context attributes, and the new context did
not have the special key we need. As all the context keys present in
stock_account are present in stock, we remove the extension. And we add
a simple test in stock.
