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
