context: stop catching RepoLookupError from namespace.singlenode()
As pointed out by Yuya, the RepoLookupError was there for catching
errors from repo.branchtip(). However, since 885c0290f7d5 (localrepo:
add ignoremissing parameter to branchtip, 2014-10-16), that should no
longer happen. I think it should now be an error if a namespace raises
a RepoLookupError, so we propagate the exception up and and make it
easy to fix, rather than trying to interpret the changeid as nodeid
prefix and raise a general "unknown revision '...'" error.
I also don't think we should catch FilteredLookupError and LookupError
from the changelog.rev() call, for the same reason as above: If a
namespace returns a node that doesn't exist, we should provide a more
helpful exception than "unknown revision '...'".

====================================
Testing head checking code: Case D-3
====================================
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.
Category D: remote head is "obs-affected" locally, but result is not part of the push
TestCase 3: multi-changeset branch, split on multiple new others, only one of them is pushed
.. old-state:
..
.. * 2 changesets branch
..
.. new-state:
..
.. * 2 new branches, each superseding one changeset in the old one.
..
.. expected-result:
..
.. * pushing only one of the resulting branch (either of them)
.. * push denied

Actual testing
--------------
$ hg push --rev 'desc(A1)'
pushing to $TESTTMP/D3/server
searching for changes
abort: push creates new remote head f6082bc4ffef!
(merge or see 'hg help push' for details about pushing new heads)
[255]
$ hg push --rev 'desc(B1)'
pushing to $TESTTMP/D3/server
searching for changes
abort: push creates new remote head 25c56d33e4c4!
(merge or see 'hg help push' for details about pushing new heads)
[255]
Extra testing
-------------
In this case, even a bare push is creating more heads
$ hg push
pushing to $TESTTMP/D3/server
searching for changes
abort: push creates new remote head 25c56d33e4c4!
(merge or see 'hg help push' for details about pushing new heads)
