Enhanced logs and workaround pushing next button

[bmarotta]

• Add different log levels
• Add more debug log messages
• Fix writing error directly to the console
• Add video information on the onSuccess event
• Avoid setting up the channel all the time when uploading multiple videos
• Added small pause (100ms) when pressing the next button repeatedly to avoid error (button apparently is not always clickable when doing it too fast)
