Argument #1 ($limit) must be of type int, null given

The error occurs because the collect method expects an integer for the $limit argument but receives null. To fix this allows $limit to be either an integer or null, defaulting to 0 if not provided.

This can only occur if the config "simple_oauth.settings" or the setting inside "token_cron_batch_size" isn't available. I wouldn't make the limit argument nullable, I rather see it addressed in the if statement on simple_oauth.module:30.

1. simple_oauth_cron() now checks for falsy values for token_cron_batch_size and defaults to 0
2. token_cron_batch_size is now a required field on the config form, since it is not nullable
3. Added the 0 limit to the description of the form item on the config form and schema

Nice work!
