Description

When searching for an empty string in experimental mode several warnings like
"Core: Error handler (FE): PHP Warning: Invalid argument supplied for foreach()"
appear in the log.
Sometimes (I think the first time searching for an empty string after flushing the caches) it even results in a php-error like
"Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1237900529: The argument "each" was registered with type "array", but is of type "boolean" in view helper "TYPO3\CMS\Fluid\ViewHelpers\ForViewHelper""

The reason for this is the return value of the function "getSearchWords" in the file SearchController.php,
which is "FALSE" instead of an array.

I can think of two possible solutions of this problem:

initializing "$sWordArray" as an empty array instead of "FALSE",
or checking whether it is an Array at the end of the function and setting it as an array if it isnt.
