Wait for a timed-out test's tear-down logic.

CHANGELOG.md

 ## 0.12.7
 
 * Add the ability to re-run tests while debugging. When the browser is paused at
   a breakpoint, the test runner will open an interactive console on the command
   line that can be used to restart the test.
 
 * Add support for passing any object as a description to `test()` and `group()`.
   These objects will be converted to strings.
 
 * Add the ability to tag tests. Tests with specific tags may be run by passing
   the `--tags` command-line argument, or excluded by passing the
   `--exclude-tags` parameter.
 
   This feature is not yet complete. For now, tags are only intended to be added
   temporarily to enable use-cases like [focusing][] on a specific test or group.
   Further development can be followed on [the issue tracker][issue 16].
 
+* Wait for a test's tear-down logic to run, even if it times out.
