[Soot-list] Determine a field's main class

[Eric Bodden]

Hi Vasco.

I think in this case you are actually already doing the right thing.
In Java, fields in subclasses shadow fields with equal names in super
classes - both fields exist in memory, and both can be accessed by the
program's code. (This is very different from methods, which have an
overriding semantics.)
