NICTA/scoobi — Issue #25: Runtime error if fromTextFile connected directly to toTextFile

A Scoobi program will crash if a file is loaded in then persisted directly without any transformation. For example:

```scala
val a = fromTextFile("hdfs://input.txt")
persist(toTextFile(a, "hdfs://output"))
```

This is an edge case as there are no `map`, `groupByKey`, etc transformations in between the *load* and *persist*.
