phases: use revision number in `_pushdiscoveryphase`

We now reach our target checkpoint in terms of rev-num conversion. The
`_pushdiscoveryphase` function is now performing graph computation based on
revision number only. Avoiding repeated conversion from node-id to rev-num.

See previous changeset updated `new_heads` for rationnal.

Again, time saved in the 100 milliseconds order of magnitude for the mozilla-try
benchmark I have been using.

However, wow that the logic is done using revision number, we can look into having
better logic in the next changesets, which will provide a much bigger speedup.

====================================
Testing head checking code: Case E-1
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.
