Delete old autotester messages

Expectations
It would be great if the autotester would delete old messages that are not useful anymore. In particular, once a build is done, the message about the start of the build is superfluous. More generally, all messages could be condensed into a single message that gets updated. This would avoid having pull requests getting flooded with a bunch of autotester runs..
