[FIX] web: various small issues in form view onchange/one2many

- Issue: Edit sale.order form view, add new line, change product who have
  taxes and click quickly on save (with slow network) => error message.
  Because some deferreds are lost.
- reduce number of reads and onchange for x2m widgets
- remove before_save method and use commit_value (the issue was that if the
  before_save and the change trigger an onchange, the onchange deferred is not
  checked before saving the content.
