Throw ExecutionException for E() syntax

I first randomly create a graph. Then when I run the following query: `g.E().outV().bothE('el0','el2','el1','el3').as('a').E().where({}.and({}.order().by(desc))).as('b').select('a').where('a',eq('b'))` is thrown with an exception. I think this query is syntactically correct, but I keep triggering this kind of problem. I generate the query based on the rule which can be refered from: https://stackoverflow.com/questions/48067834/gremlin-intersection-operation. Following this instruction, I think it's allowed to generate this kind of queries.

Expected behavior:
No exception should be expected to throw. Or futher messages or prompts should be thrown.

Actual behavior:
A `java.util.concurrent.ExecutionException` is thrown. And I'm not really sure whether this problem should happen so I report this. I succeed this kind of collection transition when replacing `g.E()` with `g.V()`. So I guess there's some problems of `g.E()` syntax. I report just in case
```
TinkerGraph exception :
java.util.concurrent.ExecutionException: org.apache.tinkerpop.gremlin.driver.exception.ResponseException: No signature of method: org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.DefaultGraphTraversal.E() is applicable for argument types: () values: []
Possible solutions: is(java.lang.Object), by(groovy.lang.Closure), use([Ljava.lang.Object, use(java.lang.Class, groovy.lang.Closure), use(java.util.List, groovy.lang.Closure), any()
```

Steps to reproduce:
We create a graph with 10 nodes and 20 edges. We try to make it clear to reproduce the bugs, {}hope{} to not cause much inconvenience to your reviewing, but we believe the problem does exist.
Following the following graph data generation query, we can reproduce the bugs:
