🐛 Cleans teleported clone

[ekwoka]

As a follow-up to #4300

When x-teleport was nested inside x-if, the use of mutateDom was preventing x-teleport clones from being cleaned up.

This just applies the same fix to immediately clean up the x-teleport clone.

Thanks @mgschoen for finding this regression.
