templater: do not use index.partialmatch() directly to calculate shortest()
cl.index.partialmatch() isn't a drop-in replacement for cl._partialmatch().
It has no knowledge about hidden revisions, and it raises ValueError if a node
shorter than 4 chars is given. Instead, use index.partialmatch() through
cl._partialmatch(), which has no such problems and gives the identical result
with/without --pure.
The test output was sampled with --pure without this patch, which shows the
most correct result. However, we'll need to switch to using an unfiltered
changelog because _partialmatch() of a filtered changelog can be an order of
magnitude slower.

N.B. bzr 1.13 has a bug that breaks this test. If you see this
test fail, check your bzr version. Upgrading to bzr 1.13.1
should fix it.
