Update to 4.1.4 causes cron error

I edited RuleStorage.php and modified:

return $this->database->query('SELECT rid FROM {' . $this->getBaseTable() . '} WHERE `limit` IS NULL')

to:

return $this->database->query('SELECT rid FROM {' . $this->getBaseTable() . '} WHERE "limit" IS NULL')

This appears to have fixed the issue, but not sure how this change might affect MySQL databases.

@tyapchyc is this ready for review?

@mandclu
yes, ready for review
Thanks

Updating this to target the 4.2.x branch, and since this hasn't been reported on any MySQL sites, classifying this as specific to PostgresSQL, even though it could obviously also pertain to other database engines.

@tyapchyc thank you for your work on this. Merged in.
