Fixes#9244
When trying to connect a Trezor account on a fresh install of MetaMask,
the radio buttons on the account selection page would not respond to
being clicked.
When debugging this, it looks like the `onChange` event was never
triggered. A radio `<input>` element should trigger `onChange` whenever
the selection state change, but seemingly this wouldn't happen if the
change in selection state was undone during the same render cycle. If
I paused at a breakpoint during the render, I could see the checkbox
get selected then unselected again without triggering `onChange`.
The simplest fix was to use `onClick` instead of `onChange`. This seems
more appropriate anyway because we're treating the radio button as a
controlled component here, so the state of the underlying element isn't
really of any concern.
