Fix incoherence with party on account move line

Since #3731 (closed), the usage of party on account move line is restricted but when migrating for older version, we could have some inconsistency.
Here is a script that tries its best to fix them.

Trying to run this script on my database resulted in this:

rhertzog@freexian:~$ sudo -u tryton ./fix_party -c /etc/tryton/trytond.conf -d tryton-test
Can not fix line: 1528
Can not fix line: 1527
Can not fix line: 1526
Can not fix line: 1525

trytond.exceptions.UserError: ('UserError', (u'You can not modify line "431 - S\xe9curit\xe9 Sociale" because it is reconciled.', ''))

Now trying patch set 3 (on Tryton 3.4):

$ sudo -u tryton ./fix_party -c /etc/tryton/trytond.conf -d tryton-testTraceback (most recent call last):
File "./fix_party", line 102, in <module>

allow_modify_party(database)
File "./fix_party", line 18, in allow_modify_party
Line._reconciliation_modify_disallow.pop('party', None)
TypeError: pop() takes no arguments (2 given)

Patch set 4 from review13871003 worked fine.
