tests: remove some unnecessary config

Some of these tests were originally split from a single file that had (and
used) these options, and some of the tests were later created by just
mindlessly copypasting the same set of options that aren't applicable to the
newly written tests.

Things removed by this patch:

- web section from tests that don't use hg serve and don't push
- phases.publish from tests that don't exchange changesets between repos
- diff section from tests that don't have any diffs
- defaults section that sets the date

The defaults section that only adds -d '0 0' to commands should no longer be
necessary because run-tests.py sets devel.default-date='0 0' since 4.3, and all
command in evolve should respect this config option.

Testing evolution of obsolete working directory
===============================================

Pulling changes from other repos can make your working directory parent (wdir)
obsolete, most probably because now it has a new successor. But there are
other cases as well where it might be pruned with no successors or split
in multiple changesets etc.

This test file deals with all the possible cases for the evolution from an
obsolete working directory parent.

.. Case A: obsolete wdp with single successor
..     Resolution : simply update to the successor
..
.. Case B: obsolete wdp with no successor (simply pruned)
..     Resolution : update to a not-dead ancestor
..
.. Case C: obsolete wdp with multiple successor (divergence rewriting)
..     Resolution : #TODO: not handled yet
..
.. Case D: obsolete wdp with multiple successor (split rewriting)
..     Resolution : #TODO: not handled yet
