Fixing bug in GetOrOpenConnection (#234)

Browse Source 
Fixes a bug where the GetOrOpenConnection method of the ConnectionService would throw if the connection didn't exist. It would yield a very unhelpful "key not found in collection" exception. The code has been updated to be much more helpful and fix the bug.
