Explicitly specifying type as Map for constructors

[silvanheller]

Changes in #324 made all constructors take Map as parameter if there are properties. However, this requires explictly searching for Map as class type in reflection. If this is not done, an exception is thrown:

This PR fixes that by explictly searching for Map constructors if there is a map passed.
