If the `$authordata` global is not set, `get_the_author()` returned `null`, causing a PHP 8.1 "null to non-nullable" deprecation notice in `ent2ncr()` hooked via `the_author` filter:
{{{
str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated
}}}
This commit updates `get_the_author()` to return an empty string if called before `$authordata` is set, bringing consistency with a few other similar functions which also return an empty string in this case:
* `get_the_author_meta()`
* `get_the_author_posts_link()`
* `get_the_modified_author()`
Follow-up to [695/tests], [2858], [11138], [12284], [20575], [34677], [44616], [53187].
