refactor: prefer checks against nullrev over nullid

A common pattern is using a changeset context and obtaining the node to
compare against nullid. Change this to obtain the nullrev instead. In
the future, the nullid becomes a property of the repository and is no
longer a global constant, so using nullrev is much easier to reason
about. Python function call overhead makes the difference moot, but
future changes will result in more dictionary lookups otherwise, so
prefer the simpler pattern.

"""collection of simple hooks for common tasks (EXPERIMENTAL)

This extension provides a number of simple hooks to handle issues
commonly found in repositories with many contributors:
- email notification when changesets move from draft to public phase
- email notification when changesets are obsoleted
- enforcement of draft phase for all incoming changesets
- enforcement of a no-branch-merge policy
- enforcement of a no-multiple-heads policy

The implementation of the hooks is subject to change, e.g. whether to
implement them as individual hooks or merge them into the notify
extension as option. The functionality itself is planned to be supported
long-term.
