TINKERPOP-1802: hasId() fails for empty collections
https://issues.apache.org/jira/browse/TINKERPOP-1802
If `hasId([])` is specified, then an `ArrayOutOfBoundsException` occurs.
This has been fixed by simply filtering out (`filter(true)` in essence) all
vertices once a `hasId([])` is reached. cc/ @rjbriody
