[PATCH] t9143: do not fail when unhandled.log.gz is not created

Commit df73af5f66 is does not let the test case fail,
when Compress::Zlib is missing.
But:
On a MacOS X 10.6 system with missing Compress::Zlib
using svn version 1.6.5 (r38866) the gz file is created.
Solution:
Check for the existance of the unhandled.log.gz file.
