Add test cases for new connection logic

This patch adds test cases for the new connection logic:
- connect_multiple checks that nitrocli aborts if more than one Nitrokey
  device is connected and no filter is set.
- connect_serial_number checks that we can use the --serial-number
  option to connect to all supported Nitrokey devices.
- connect_wrong_serial_number checks that nitrocli aborts if it can’t
  find a device with the requested serial number.
- connect_model checks that we can use the --model option to select the
  Nitrokey device to connect to, and that nitrocli aborts if it finds no
  matching device or multiple matching devices.
