Incorrect toggling behavior with "auto switch off Yubikey" enabled

[cruisercohen]

I've been experiencing a bug with the toggling behavior when "Automatically switch off Yubikey" is enabled.

Reproduction steps:

• Configure with the “Auto switch off yubikey” option
• Enable manually with "Enable Yubikey" or hotkey
  • Yubikey is enabled and works
• Disable manually by unchecking"Enable Yubikey" or using hotkey
  • Yubikey is disabled and does not emit one time passords
• After 10 seconds the auto-disable happens, which actually re-enables the key (though visual indicator shows disabled)
  • Yubikey is enabled again and will send out one time passwords
  • Note that the toolbar icon remains in disabled grey state even as the Yubikey continues to work

Workaround:

• Manually enable with "Enable Yubikey" or hotkey
  • Yubikey remains enabled, this seems to have "reset" things
• Wait for the auto-disable
  • Yubikey is disabled and will not send out one time passwords
• Never manually disable Yubikey
