    Retain sheet protect options throughout unprotect/protect session
    
    Currently, unprotecting a sheet clears the protection options it
    had (i.e. if to allow users to select protected/unprotected cells).
    So, protecting next time requires setting these options again.
    Unprotecting a sheet usually happens when author edits e.g. a form
    and intents to re-protect it when the edit is done, so it would be
    handy to restore previous flags as they were before.
    
    This patch allows saving the protection settings by using
    current ScTableProtection copy with its protection set to appropriate
    value, instead of new clean ScTableProtection or nullptr.
    
    This does not allow to save the flags between edit sessions if the
    protection is unset.
