[FIX] {sale_}purchase{_stock}: select sellers depending on date

Commit 72a17bafba6e7 force the PO `date_order` to be >= at ` today() to
ensure the select_seller method take the right seller price. This
introduces an error in the MPS module that may need to create PO in the
past.

Instead, this commit patch the call to `_select_seller` to take at least
`today()`
