Add new test to ensure that reload after chrome://kill works.

https://crrev.com/c/2006890 will reland a CL that broke this.

This test "correctly" fails when patched onto
f4c4a4aa however it passes when patched
onto the reland. Manual testing of the reland also does not trigger
the bug, so I guess something changed but having an automated
regression test seems wise.
