[tizen] Add copy ctor to tizen.Bundle.

This will simplify the implementation of API methods which
need to accept both plain json object and tizen.Bundle.
In example: function sendCommand(..., data) { var d = new tizen.Bundle(data); }
instead of manually having to check if data is a tizen.Bundle or object.

[Verification] Added new test case for this constructor, all existing tests passes.
