Fixes the travis build

Move up building in scalding to 2.10.4 

--> Is backwards compatibility with long file names broken? (Would seem strange since the assembly plugin version should be the same)

--> Cuts down on both the assembly and test noise during build 

--> Fixes a scald.rb issue when dealing with 2.10.4, the find_dependencies command appears to return different in 2.10.4 

Fixes #943
