Queue up messages to send ot the cloud server which accumulate before 
the connection is ready. Add tests for new/updated functionality.

Add unit tests for disconnecting from cloud when viewing a project in editor mode without the ability to save.

The functionality was all moved to the Controls container, these containers are no longer used

Set VM's cloud provider to null when disconnecting from the cloud server. Add unit test for disconnecting on unmount.

Add test for ensuring that cloud connection does not happen just because of a project id change. isShowingWithId must also be true.

Fix issue where regular cloud variable messages were throwing uncaught Json parse errors because of a newline being at the end of the message. Add test that fails without the bugfix.

Uses randomized duration between [0, 2^k-1] where k is the connection attempt number, maxed out at 5.

I had to rework the tests quite a bit to make this easy to test, to work around the timeouts and the randomization.

Added a unit test and covered the other case (not used) where you might be trying to update the index zero of a list

This prevents a tutorial with no urlId being returned in the case of no tutorial query param
