hgweb: handle exception of misconfigured path on index page

If hgweb.config contains wrong path mapping, hgweb causes internal server
error on repository index page.

This patch changes makeindex() to ignore RepoError, because it looks to be
designed to suppress configuration error.

# create a little extension that has 3 side-effects:
#   1) ensure changelog data is not inlined
#   2) make revlog to use lazyparser
#   3) test that repo.lookup() works
# 1 and 2 are preconditions for the bug; 3 is the bug.
