[binder] binding customer_group_id is zero failed

[fevxie]

Hi, team:

 when I import partner.category  I find when the search result customer_group_id is 0 the job is failed. then I check the code,  I find in when I bind the magento_id with binder_id  the code has a assert sentence in the magentoerpconnect module binder file line 123:

assert external_id and binding_id, (
"external_id or binding_id missing, "
"got: %s, %s" % (external_id, binding_id)
)

then the external_id value is 0 and this sentence is not passed.

I think maybe this is a bug for every object import to OE when the magento_id is zero.
