    Properly compute resource_properties pickle

    When you check for resource_properties size when storing event, we use
    the regular pickle module with the default protocol. Sqlalchemy uses
    cPickle if available, with the highest protocol, which can result in
    fairly different storing size. Use that instead, this should remove the
    last occurence of the storage bug.
