    gitweb: fix tests on uninitialized hash indexes to avoid uninitialized
    value warnings in server log
    
    It's happened that I tried to solve lots of meaningless warnings in web
    server error log.
    
    I think it makes no sense to spam error log with warnings about
    uninitialized value when trying to run careless tests on undefined hash
    indexes.
    
    This is a simple fix that I did long ago that check carefully the index
    before running tests on it.
    
    I added myself as warning fix author as well.
    
    My goal is to avoid re-applying the patch on each distribution update.
    
    The warning message fixed in web server error log : Use of uninitialized
    value $params{"action"} in string eq at gitweb.cgi line 1377
