 When sending an empty value to wp_localize_script() a warning is issued
 stating:
 Cannot assign an empty string to a string offset

 How to reproduce:
 call wp_localize_script() like this:

 {{{#!php
 <?php
 wp_localize_script('my_valid_handle', 'my_variable_name', '');
 }}}





 Analysis:
 Sending an empty value for a variable is perfectly legit so there is no
 problem with the input.
 The problem lies here: The code at line 449 treats $l10n forcefully as an
 array but the code at 454 wrongfully assumes $l10n is an array without
 checking.
