Title:
  [account] onchange_line error when debit and credit values not changed

Status in OpenERP Addons (modules):
  New

Bug description:
  The following error is generated if a journal item (debit/credit line)
  is changed on a journal entry, but no change is made to the debit and
  credit values:

  Server Traceback (most recent call last):
    File "/home/jjesudason/Documents/Development/openerp/trunk/web/addons/web/common/http.py", line 592, in send

    File "/home/jjesudason/Documents/Development/openerp/trunk/server/openerp/osv/osv.py", line 176, in execute
      res = self.execute_cr(cr, uid, obj, method, *args, **kw)
    File "/home/jjesudason/Documents/Development/openerp/trunk/server/openerp/osv/osv.py", line 164, in execute_cr
      return getattr(object, method)(cr, uid, *args, **kw)
    File "/home/jjesudason/Documents/Development/openerp/trunk/addons/account/account.py", line 1367, in onchange_line_id
      balance += (line[2]['debit'] or 0.00)- (line[2]['credit'] or 0.00)
  KeyError: 'debit'

  The problem is with the onchange_line method in account/account.py:

      def onchange_line_id(self, cr, uid, ids, line_ids, context=None):
          balance = 0.0
          for line in line_ids:
              if line[2]:
                  balance += (line[2]['debit'] or 0.00)- (line[2]['credit'] or 0.00)
          return {'value': {'balance': balance}}

  This should do the following instead:

      def onchange_line_id(self, cr, uid, ids, line_ids, context=None):
          balance = 0.0
          for line in line_ids:
              if line[2]:
                  balance += (line[2].get('debit') or 0.00)- (line[2].get('credit') or 0.00)
          return {'value': {'balance': balance}}

  Steps to reproduce:
  1. Duplicate a Journal Entry.
  2. Edit one of the lines on the journal entry and only change the account.
  3. Save the line.

  This will generate the error message.
