> tail() step inside repeat() is not properly resetting per iteration.
> Consider the following queries on the modern graph on 3.7.x
> {code:java}
> gremlin> 
> g.withoutStrategies(RepeatUnrollStrategy).V(1).repeat(__.both().order().tail(2)).times(2)
> ==>v[4]
> ==>v[6]
> {code}
> {code:java}
> gremlin> g.V(1).both().order().tail(2).both().order().tail(2)
> ==>v[5]
> ==>v[6]
> {code}
> The unrolled version doesn't match the repeat() version because tail() is 
> recalculated on each call to processNextStart(). The tail() is being 
> calculated too frequently even though there are still output traversers 
> remaining from the previous calculation.
