checkheads: use 'nodemap.get' to convert nodes to revs

We are about to call 'torev' on node that might be locally missing. In this
case, 'nodemap.revs' will return None (something valid in our usecase) while
'changelog.rev' would raise an exception.

We make this change in a distinct changeset to show it does not impact the
tests.

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.
