Should winetest retrieve msi log file on msi test failures?

[Dan Kegel]

Looking at test.winehq.org's XP results, it seems we're doing
quite well; some of the remaining failures seem to be unusual situations.
For instance:

msi:msi.c is passing flawlessly on 7 out of 10 computers,
and on one of the computers, it has just one failure:
http://test.winehq.org/data/8f829034f3fe4da3e7adce2f4685e10ba2e2fe82/xp_fg-winxp-ie7/msi:msi.html
says
dlls/msi/tests/msi.c
msi.c:254: Test failed: wrong error 1618

1618 is ERROR_INSTALL_ALREADY_RUNNING.

Say, can winetest retrieve and display the msi log file on failure?  That
might be informative...
