[gnome-shell] calendar: Grab key focus when user changes day

    calendar: Grab key focus when user changes day
    
    When the user changes the active day by mouse click or keyboard focus
    plus key press on a day in the grid, always move the keyboard focus to
    the newly activated day.
    
    This basically restores functionality that was introduced in commit
    31478e9fb441 but got lost again in the re-factoring in commit
    cc4659f5c697.
