Implementation of hook_install is broken in gigya_raas module

I see in logs `[warning] sprintf(): Too few arguments gigya_raas.install:31`

Drupal logger is psr-3 compliant so interpolation must be done when log records displayed

Also it missing to uninstall the added fields, so this fixes re-install module issues
