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.
