hww: smarter auto-selection of which device to pair with

scenario1:
- 2of2 multisig wallet with trezor1 and trezor2 keystores
- only trezor2 connected
- previously we would pair first keystore with connected device and then display error.
  now we will pair the device with the correct keystore on the first try

scenario2:
- standard wallet with trezor1 keystore
- trezor2 connected (different device)
- previously we would pair trezor2 with the keystore and then display error.
  now we will prompt the user to select which device to pair with (out of one)
