Fix detection of hardware keys in keepassxc-cli

* Split calls to finding hardware keys into sync and async methods. This has the side effect of simplifying the code.
* Check for keys before performing challenge/response if no keys have been found previously.
* Correct timeout of user interaction message to interact with the hardware key.
* Correct error in TestCli::testYubiKeyOption
