mod_http_muc_log: Remove dead code This might be something left over since a different variant where the loop went like `for n = i-1, i-100, -1 do ... end` i.e. it went trough a fixed number of items instead of all the page until the current message. Then it would have needed something to stop going over the end, but since the checks are simple it shouldn't be much of a problem looping over even a very busy day.

summary: Workaround for servers doing EXTERNAL without proper stream headers
...

Introduction
============

This module is a workaround for servers that try to do s2s
authentication with certificates and SASL EXTERNAL, but do not send
correct stream headers. Notably Openfire versions since 3.7 or 3.8.
