Chrome launches with two tabs

When I run with `--browser=chrome` it opens with the "pick a search engine" modal tab which prevents tachometer to work: ``` npx tachometer destr.html no-destr.html --browser=chrome [----------------------------------------------------------] launching chromeRunning benchmarks [----------------------------------------------------------] warmup 1/2 chrome destr.htmlError: Expected only 1 open tab, got 2 ```
