Don't load transports, until they are used.
Don't load transports, until they are used.

I'm working on a solution for react-native, and for that I am build my "own" transport plugin. It would make my life a lot easier if the other transports isn't loaded, when I'm using mine.
Also:
`transInfo.url` was never used.
