While hunting for bugs (see thread in #601) I found that:
hasData_property of chained batch is unused. Though LevelDB seems to be fine with writing an empty batch, this PR skips that ifhasData_is false, so that the behavior is symmetric withbatch([])(array-form) and withleveldown@4x.batch([])(array-form) isn't asynchronous if the array is empty.
