    Put focus on password field when principal is set
    
    In the Leash "Get Ticket" window, under some user-customized
    configurations, the principal field can be pre-populated.  In this case,
    it makes sense for the default focus to be on the password field,
    since most users will only be using a single principal and should
    go directly to typing their password.
    
    The focus was already set to the password field in the case when
    the principal was not modifiable (such as when the "Get Ticket" dialog
    was opened by an application requesting a specific ticket).
    
    (cherry picked from commit 50b3bba748084c99a339bd526ad47ecfccc09472)
    
    ticket: 8032
    version_fixed: 1.13.3
    status: resolved
