In commit 878d58d23a, a new parameter was
added to commitlog::descriptor. The commit message says that "It's default
value is a descriptor::FILENAME_PREFIX." while in reality, it did not have
a default value and compilation of tests/commitlog_test.cc broke, because
it didn't specify a value.
So this patch adds a default value for this parameter, as was suggested
by the original commit message.
