resource_create crashes on ValidationErrors with KeyError: 'resources'

[seanh]

ckan/logic/action/create.py:resource_create():

try:

pkg_dict = _get_action('package_update')(context, pkg_dict)

except ValidationError?, e:

errors = e.error_dictresources?[-1] raise ValidationError?(errors)

This assumes that package_update always returns an error dict with 'resources' in it. This assumption doesn't hold.
