Prevent fatal error with newer PHP versions

[KZeni]

Simply using count() throws an error if that variable is empty since something that's empty isn't seen as countable (TypeError). Check if it's not empty first to avoid the error.

Also did a very minor version bump as it's a bit of a hotfix at the moment.

Hopefully this is something that could be given a few minutes to merge (the fix being very harmless & straightforward) and release on WP.org as it is causing fatal PHP errors on sites that might have this plugin installed that then are doing the right thing in updating their PHP version over time.

Giving this topic a bump since it's been more than a year to officially adopt a patch that adds PHP 8.0+ support by way of editing one line of code to first make sure a variable isn't empty before trying to use count on it (something PHP 8.0 introduced as needing to be done; likely for performance reasons [speed up count by not doing that check every time & instead have the developers do that check themselves if/when needed.])

https://wordpress.org/support/topic/prevent-fatal-error-in-php-8-0/ is where this was talked about on the WP.org support forums, btw. It's since been closed to inactivity, but hopefully, it can still be addressed here with a new version release. Better late than never.

Otherwise, I'm wondering if this plugin should be taken down from WP.org and/or archived on GitHub (or transferred to a new maintainer / forked / etc.) if it's honestly not being supported anymore with PHP 8.0+ effectively being a requirement (per https://www.php.net/supported-versions) and this one quick patch to support that isn't being adopted (plugin might as well not be offered if it only supports PHP versions that really shouldn't be used anymore.)

Okay, how is this still not addressed? It's such a quick fix (merge PR & release the new version on WP.org) for something that renders this plugin unusable as more & more people start using PHP 8.0+.
