Wrong links when installed in a subfolder

Hei

I noticed, that when I have WordPress installed in a subfolder, the links do not work correctly.

Admin Bar -> Noted Visual Feedback
mypage.com/wordpress becomes mypage.com/wordpress/wordpress/?noted

Frontend -> Noted view -> Dashboard
mypage.com/wordpress_12345?page_id=10&noted-> mypage.com/wordpress/wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F

Backend -> Noted Visual Feedback -> Dashboard / Backend -> Noted Visual Feedback -> Pages
Same problem here, the subfolder gets added twice.

This happens because:

- home_url() already includes the subfolder: https://example.com/wordpress
- remove_query_arg() / add_query_arg() return the path from $_SERVER['REQUEST_URI'], which also includes the subfolder: /wordpress/my-page/?noted=

So home_url('/wordpress/my-page/?noted=') becomes https://example.com/wordpress/wordpress/my-page/?noted=

Also, when closing the overlay, the admin bar stays hidden. It can be fixed by just reloading the page, but is not ideal.

Best, Daniel
