Perform null check on timezone_identifiers_list_cache in AWLUtilities
Fixes #29
- After calling
timezone_identifiers_list()
check if the variable$timezone_identifiers_list_cache
is false and set the var to [] in this case. - When accessing
$timezone_identifiers_list_cache
perform a null check to prevent an exception if the global has not been initialized.
