> Flink runner sends bad flatten to SDK

> For a Go flatten test w/ 3 input, the Flink runner splits this into 3 bundle
> descriptors. But it sends the original 3-input flatten but w/ 1 actual input
> present in each bundle descriptor. This is inconsistent and the SDK shouldn't
> expect dangling PCollections. In contrast, Dataflow removes the flatten when
> it does the same split.
