Minimise config updates when checking cron jobs
Simplify cron array comparison

This works fine - I had not thought about how arrays are compared. Using "==" checks that the key/value pairs match in both arrays, regardless of the order the arrays happen to be in, which is what we want here.
Using "===" would insist that the key/value pairs are also in the same order in the array and that the types and everything match identically, which we do not require.
