run-tests: check if stream is a tty before using color

Previous implementation (e80041832eec) checked only if sys.stderr was a tty
which was less general. Also makes sure that colors is never used if pygments is
not available, irrespective of --color flag value.

====================================
Testing head checking code: Case B-2
====================================

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 B: simple case involving pruned changesets
TestCase 2: multi-changeset branch, head is pruned, rest is superceeded, through other

.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * old head is rewritten then pruned
.. * 1 new branch succeeding to the other changeset in the old branch (through another obsolete branch)
..
.. expected-result:
..
.. * push allowed
