Fix arg name inference for array types

If you are extending a class and haven't implemented an abstract method
that contains an argument that's an array type,
and the array element type is a well-known type such as `java.lang.Object`,
this will now properly use the suggested name from JDT.

eg. parent signature `abstract public void useArray(Object[] arg1)`

child signature `public void useArray(Object[] o)`

`o` is the JDT suggested name for objects.
