test_runner: remove redundant report call

This commit removes a redundant call to `reportStarted()`. It is
redundant because a few lines down, `subtest.finalize()` is
called. `finalize()` will find the first test that is ready to
report its data, and then call `report()`, which also calls
`reportStarted()`. This will trigger the `'test:start'` as high
up the test tree as necessary.
