Group update via API fails validation with organization and publisher profile enabled

[johnglover]

Reported on IRC by 'floapps'.

• when posting a group update with {packages: [package-1, package-2, etc.]}, getting ValidationError?: {'Packages': {'name': Missing value?}}, although package objects did contain a name field
• same API call worked with organization and publisher profile disabled
• also worked if added a form_to_db_schema_options function which used default_update_group_schema for api updates instead of default_group_schema
• tried on both 1.7 and 1.7.1b

Works for me on 1.7.1.

Perhaps floapps was using older groups (of type 'group' instead of 'organization') and/or didn't add a user to the group?
