Improved bug board automatization

In our bug board, issues were moved into the 'Waiting for Engineering'
column when the author of an issue responded. The column move was made
if the issue was tagged with the label 'waiting-for-author'. However,
sometimes this label was not added to the waiting issues. As a result,
the issue was not moved to the right column when the author responded.

This PR replaces the error-prone label check with a check in which
column the issue is.
