post tags array safety checks

[kyrahabattoir]

Just close this if i'm wrong but...

at https://github.com/simonfrey/mastodon_wordpress_autopost/blob/c24f4cef9582d676857690e1988551953afae713/autopost-to-mastodon/trunk/mastodon_autopost.php#L544

shouldn't

        $post_tags = get_the_tags($id);
        if (sizeof($post_tags) > 0) {
            if ($post_tags) {

be instead

        $post_tags = get_the_tags($id);
        if ($post_tags) {
            if (sizeof($post_tags) > 0) {

That is, check if post_tags is not null and THEN check its length rather than the other way around?

Did you test it how it behaves with you change? If not please do so and then we know best if it still works as intended :D
