Using an external URL was causing the browser to actually attempt to
connect to it. Sometimes, a response from the external URL will take
more than 30 seconds to return a response causing the page to never fire
the load event before playwright's timeout is reached.
Creating the post ahead of time ensures it's ready when we want to visit it. There's also no need to reload the user as we do a visit which triggers a full page refresh.
register_editable_user_custom_field is "singular" and only access one
"custom field" as a parameter.
the fix was to call register_editable_user_custom_field for each custom
fields this plugin uses.
also added a bunch of system specs to ensure the basics of the plugin
actually works.
