[OC-3564] update spec to not depend on ActiveSupport
[OC-3564] update spec to not depend on ActiveSupport

Spec in question was improperly assuming the `blank?` method exists for
Object instances.  This method is not part of core Ruby and actually
only ships as part of ActiveSupport. ActiveSupport was being loaded when
by other specs that rely on treetop (which has ActiveSupport as a
dependency). An equivalent test would be checking that a value is not
nil? or empty?.
