The NullableCoder does not encode any elements after the subcoder
encodes the input value for non-null values. As a result, the subcoder
should see the entire input stream if it is available.
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/tgroh/incubator-beam nullable_non_nested
Alternatively you can review and apply these changes as the patch at:

> NullableCoder should encode using the context given and not always use the nested context. For coders which can efficiently encode in the outer context such as StringUtf8Coder or ByteArrayCoder, we are forcing them to prefix themselves with their length.
