[FIX] stock: redirect move lines location dest

Changing the destination location on a picking will:
- Change the dest location of its stock.move
- Not change the dest location of stock.move.line

So it the picking has been reserved, everything will
be send to an incorrect location. On top of it, the
system prevent to select a destination location that
is not a child of the move dest location.

This commit, redirect the location dest on stock.move.line
when the dest location on stock.move change.
