Show Logs for for every build of a leeway package if it's build multiple times.

Werft ran leeway twice, resulting in the package "components:all" building twice.

However, Werft's UI shows only one run and log-output of "components:all".

It would be nice if Werft would run both log outputs. Maybe as children of the "build" phase (which invokes leeway). Currently, it's shown as a sibling.
