Bug description
---------------
`account.analytic.contract.line` inherits
`account.analytic.invoice.line`
`account.analytic.invoice.line` defines field `analytic_account_id`:
- comodel='account.analytic.account'
`account.analytic.contract.line` redefines field `analytic_account_id`:
- comodel='account.analytic.contract'
On attempt to extend `account.analytic.invoice.line` model adding
field that depends on `analytic_account_id.date_start`
Odoo fails to update, because it adds this field to
`account.analytic.contract.line` through inheritance,
and `account.analytic.contract` model have no this field.
What is done
------------
Change inheritance order:
- `account.analytic.invoice.line` inherits
`account.analytic.contract.line`
- no file renames at this stage (this wil be done in next commit)
