- If board does not exist, redirect to All Boards page, at all Wekan platforms.

So now at Sandstorm when loading Wekan grain, if first Sandstorm board is found,
  it is opened. If first Sandstorm board is not found (it's deleted or archived),
  then redirect automatically to All Boards page.

Closes #3132
