run-tests: allow run-tests.py to run tests outside current directory

When reloading tests, run-tests.py was assuming that it could look
up the test by the basename, which only works if you are running
tests which are in the current directory.

This patch changes that lookup to use the full path. This is all
that was needed, and does not appear to cause any problems for
any of the existing testing work flows based on running the
suggested commands at the top of run-tests.py.

Motivation: In order to test Mercurial with Hypothesis (according
to https://www.mercurial-scm.org/wiki/HypothesisPlan) it is
useful to be able to generate temporary test files and execute
them. Generating temporary files in the tests/ directory leads to
a lot of suboptimal clutter.

Test merge states

  $ hg ci -m manychanges

  * files updated, 0 files merged, * files removed, 0 files unresolved (glob)
  $ echo c >> b2
  $ hg ci -m diverging b2

  merging b2
  warning: conflicts while merging b2! (edit, then use 'hg resolve --mark')
  * files updated, 0 files merged, 1 files removed, 1 files unresolved (glob)
  use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon

  $ fileset 'resolved()'
  $ fileset 'unresolved()'

  $ echo e > b2
  $ hg resolve -m b2

Test subrepo predicate

  $ hg init sub
  $ echo a > sub/suba
  $ hg -R sub add sub/suba
  $ hg -R sub ci -m sub
  $ echo 'sub = sub' > .hgsub
  $ hg init sub2
  $ echo b > sub2/b
  $ hg -R sub2 ci -Am sub2
  adding b
  $ echo 'sub2 = sub2' >> .hgsub
  $ fileset 'subrepo()'
  $ hg add .hgsub
  $ fileset 'subrepo()'
  sub
  sub2
  $ fileset 'subrepo("sub")'
  sub
  $ fileset 'subrepo("glob:*")'
  sub
  sub2
  $ hg ci -m subrepo

Test that .hgsubstate is updated as appropriate during a conversion.  The
saverev property is enough to alter the hashes of the subrepo.

  $ hg init ../converted

  >      sub ../converted/sub

  $ hg --config extensions.convert= convert --config convert.hg.saverev=True  \
  >      . ../converted
  scanning source...
  sorting...
  converting...
  4 addfiles
  3 manychanges
  2 diverging
  1 merge
  0 subrepo
  no ".hgsubstate" updates will be made for "sub2"
  $ hg up -q -R ../converted -r tip

  a

  $ oldnode=`hg log -r tip -T "{node}\n"`
