<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Upgrade: Prevent warnings upgrading cron array.
An unvisited site may have an undefined cron array, resulting in `_get_cron_array()` returning the value `false`. Previously this would trigger warning in `upgrade_590()` as the function assumed `_get_cron_array()` would alway return an array.
No database version change is required as the upgrade routine was successful on sites with a cron array during 5.9.0. On sites without a cron array, the error has already been thrown if they are running db version 51917. This fix is only required for new sites or those upgrading that have skipped 5.9.0.
