Fixes #4550. Ensure that `detached` cannot run before an element is “readied.” This fixes an issue that allowed an element with `disable-upgrade` to process the `detached` callback.

Avoid calling `detached` before an element is readied. When an element is readied, if attachment is pending only call `attached` if the element is actually attached.
