preexisting point, but why are we using generate_string?

In this location, why not just '❤❤❤❤❤❤❤❤❤' directly?
In other locations, just '\ucode'.repeat(123).

OK to ignore in this patch.

Changed it to 'LE Device' since there is no need for the unicode characters.
Not sure why we added that function O.o http://crrev.com/2858183002

+  return setUpSystemConnectedDevice({name: device_name})
     .then(() => requestDeviceWithKeyDown({acceptAllDevices: true}))
     .then(device => {
       assert_equals(device.name, device_name);
