Attempting to define a third party performance check in a plugin leads to a coding error when attempting to view the Performance check report.

Exception - Cannot access protected property tool_xxx\check\enabled::$component

Stack trace:

• line 82 of /lib/classes/check/manager.php: Error thrown
• line 56 of /lib/classes/check/manager.php: call to core\check\manager::get_performance_checks()
• line 72 of /lib/classes/check/table.php: call to core\check\manager::get_checks()
• line 35 of /report/performance/index.php: call to core\check\table->__construct()

The manager attempts to directly set $check->component, whereas it is correctly accessed using the set_component() method for status and security checks
