Fixed: Prevents to uselessly clutter the logs up with SetTimeZoneFromBrowser errors (OFBIZ-13061)

Fixes this error found in trunk demo log.
SetTimeZoneFromBrowser.groovy]: (Cannot get property 'userLoginId' on null object)
It happens, at least with webpos/control/SetTimeZoneFromBrowser
It's just to prevents cluttering the logs.
