PROBLEM: It is not possible to retrieve traces from swarming with
--gtest_repeat.

For a file to be retrievable from swarming, it must be placed in
${ISOLATED_OUTDIR} but specifying anything for --enable-tracing-output
disables the unique-filename-per-test behaviour.

With this change it becomes possible to do e.g.

tools/mb/mb.py run ... \
  --gtest_filter=WebNavigationApiTest.Crash \
  --gtest_repeat=100
  --enable-tracing=*,disabled-by-default-toplevel.flow \
  --enable-tracing-output='${ISOLATED_OUTDIR}/'

and have unique files for each test that are retrievable with swarming
collect.

Also drive-by fix typo in name of function.
