expire and reset open password provider on second click or on click on another provider

If a password is selected and shortly after that another password, the first password can not be copied until its timer is expired. There maybe occasion where this is required, and in those cases, the second password would erroneously be used when the user has clicked the first password again. Therefore this PR expires all open passwords (should only be one) on click of any password entry and activates the clicked entry if it was not active before.
