Creating a new key pair can take 1-2 seconds. So it could happen that the user click the "Reset password" button again which can lead to many nasty things, e.g. we could create two new key pairs in parallel.
This patch wil warn the user of the consequences when resetting the password and requires checking a checkbox (as we had in the past) to reset a password.
Furthermore I updated the code to use our new classes and added some unit tests for it 👯
