Fix stdout test when a php version isn't defined in php.conf
Fix stdout test when a php version isn't defined in php.conf

Case EA-5152: 2 fixes, various cleanups
 1. Fix: This script used to issue a warning when the "handler"
    being assigned is different than previous (or even not
    defined).  A later change updated the code to only issue
    the warning when the handler was changed from an existing
    value, instead of being freshly installed.
 2. Fix: require_ok() now generalized using FindBin module and
    within a startup Test::Class hook
 3. Removed unnecessary occurences of other require_ok() tests
 4. Added note() usage for readability
 5. Added return statements
 6. Added copyright
