[PATCH 06/13] do not assert on legitimate re-execution of tasks

["'Felix Moessbauer' via isar-users" <isar-users@googlegroups.com>]

When running with sstate cache and a bitbake hashequiv server, tasks can
be re-executed even though this does not indicate false sharing of a
WORKDIR. The false-sharing detector in isar-events must not assert on
these cases.
