rawurlencode($username) was called on line 38 (encoding the username),
then rawurlencode($matrixId) was called on line 39 encoding the already-
encoded string — causing %20 to become %2520 for usernames with special
characters. Fixed by building $matrixId with the plain username and only
encoding the full Matrix ID once in the URL path.
