SI-8004 Resolve NoPosition error for applyDynamicNamed method call
Previously, there were no positions created for the tuples that are generated while doing the transformation for an applyDynamicNamed call. This led to an NoPosition error in scalac when one tries to show position information in the AST. Furthermore, this simplifies semantic highlighting in the scala-ide because no position information for color ranges have to be created anymore.
