I found this bug in the Loops extension while upgrading Mediawiki from 1.27.1 to 1.28.0

To reproduce the bug, loop over 100 times:

{{#loop: counter
  | 1
  | 101
  | <nowiki/>
{{#var:counter}}
}}

Actual Result is an error: [adb78e11d1356ec816bc8e1c] /w/index.php?title=User:Pfarrar/sandbox&action=submit Error from line 360 of /home/wiki/wiki/wiki/extensions/Loops/Loops.php: Call to undefined method Message::escape()

Expected 'loops_max' message ("Maximum number of loops have been performed").

I was able to fix this in Loops.php line 360.
