Console error messages displayed

[jgadsden]

We get some console error messages when TD starts up. It is annoying and worrying for the user when these are briefly visible in the main application window. We need to either:

• fix the error + warning messages
  or
• stop them appearing on the main window

Thanks @derekhillhp for reporting this

After some trial and error, I was able to capture a screen shot of the startup messages.

This is running on OS X Mojave 10.14.6

The error messages are due to auto-update not working correctly, subject of PR #102 . Once this is merged in then these error messages are no longer displayed.
