fix: joins in join maps get added correctly to a bridge

When Essentials moved to using `System.Reflection` instead of the Crestron classes, there were some leftover `GetType` calls that were no longer necessary. These extra calls were preventing things from getting the correct type.

Join Map printing was also fixed to print out in an actual readable fashion.
