Search module shows JS error message when MySQL timezone tables are not loaded

[ravihansa3000]

If the MySQL timezone tables are not loaded, JS error message is shown when trying to search for an existing missing person.

The module should check whether MySQL timezone tables are loaded and warn the user if they're missing. JS error message should not be thrown at all.

I had an old version of Vesuvius (sahana-agasthi-portable2). I tried this out on that, but there was no such error on the previous one. It works well, even though I completely removed timezone tables.
(Just sharing the experience.)
