DRILL-6124: Fixed possible NPE when no injection site is defined for …
…"partitioner-sender-latch" in PartitionerDecorator.

injector.getLatch(context.getExecutionControls(),
"partitioner-sender-latch");
```
Can return null if the user does not have the appropriate injection defined
in their config.

> Project: Apache Drill
> Issue Type: Bug
> Reporter: Timothy Farkas
> Assignee: Timothy Farkas
> Priority: Major
>
> In PartitionerDecorator we get a latch from the injector with the following
> code.
> testCountDownLatch = injector.getLatch(context.getExecutionControls(),
> "partitioner-sender-latch");
> However, if there is no injection site defined in the user's drill
> configuration then testCountDownLatch will be null. So we have to check if it
> is null in order to avoid NPE's
