hgweb: fixes traceback for invalid files by removing top-level template
The top-level 'comparison' template was not really needed, and it also caused a
traceback to be shown for inexistent files (as reported by Ross Lagerwall).
Getting rid of it makes the overall templating structure simpler and causes
invalid files to be handled nicely.
