Classic Test Runner: use `runIsolated` by default

The link "Debug this campaign" on attester status page
now leads to the page which runs each test in isolation,
which helps avoiding certain errors if the test modifies
global execution environment.

fix #16 task restart mechanism when a browser is disconnected

Before this commit, when a browser was disconnected while executing a
task, the task was considered as failed.
This commit automatically queues again those interrupted tasks so that
they are executed again (with a maximum number of restarts, so that
tasks which make a browser crash do not lead to a never ending campaign).
