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)

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing:

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
