- Fixed the clara.rules.dsl/parse-condition-or-accum fn to only put the :result-binding key in the resulting parsed accumulator if there is a result binding for the accumulate condition.  This is necessary to match the clara.rules.schema/AccumulatorCondition defined.
- Added test to verify that accumulate works in a rule without a result binding given.
