repoview: stop recomputing cached key in all case
As explained in the comment, we were computing the key of the cache value every
time because of some obscure MQ test failure. I've dropped that code and ran the
test again that failure is gone. I assume some transaction cleanup got rid of
it.
So we are dropping that code. This provide a significant speedup.
Testing `hg log` on Mozilla-central this reduce the time spent on changelog
cache validation by a third:
before: 19.5s of 80s
after: 12.2s of 69s
(With stupid python profiler overhead)
