revset: remove existence check from min() and max()

min() and max() would first do an existence check. Unfortunately existence
checks can be slow in certain situations (like if the smartset is a list, and
quickly iterable in both ascending and descending directions, then doing an
existence check will start from the bottom, even if you want to check the
max()).

The fix is to not do the check, and just handle the error if it happens. In a
large repo, this speeds up:

hg log -r 'max(parents(. + .^) - (. + .^)  & ::master)'

from 3.5s to 0.85s. That revset is contrived and just for testing. In our
real case we used 'bundle()' in place of '. + .^'

Interesting perf numbers for the revset benchmarks:

max(draft() and ::tip) =>  0.027s to 0.0005s
max(author(lmoscovicz)) => 2.48s to 0.57s

min doesn't show any perf changes, but changing it as well will prevent a perf
regression in my next patch.
