The behat for tool_task was no longer working in Clean & More due to the menu changes.
This updates the affected steps on Master only as 49399 was a master only fix.
This test cannot be run on Behat anymore as the "Run now" feature
depends on $CFG->pathtophp. Even if it's set, the task executed via
"Run now" will be executed for the installed site itself and not on the
Behat test site.
