 While debugging some locale-related oddities, I ran into
 `sanitize_locale_name()` happily accepting arrays.

 {{{
 wp> sanitize_locale_name( [ 'test at test' => 'test at test' ] );

 array(1) {
   'test at test' =>
   string(8) "testtest"
 }
 }}}

 This is not uncommon for WordPress functions that rely upon
 `preg_replace()` and a number of other sanitize functions behave
 similarly.

 I would expect an array input to return either `''` as `array( .. )` is
 not a valid  string.
