[PATCH] t6019: avoid refname collision on case-insensitive systems

[Thomas Rast <trast@student.ethz.ch>]

The criss-cross tests kept failing for me because of collisions of 'a'
with 'A' etc.  Prefix the lowercase refnames with an extra letter to
disambiguate.

This fixes the tests on OS X.  Together with Peff's fix to the poll
issue, it now tests clean again.
