Aaron Jorbin e2104af75e Widgets: Prevent infinite loop in PHP8+ if the URL for the widget instance is incorrectly defined ...

This checks to make sure $link isn't empty before attempting to manipulate it.  A simple test to demonstrate this can be seen at https://3v4l.org/PgSZg. Unit tests for both what already works and what is fixed by this change.

Fixes #53278.
