Update InArray.php

in InArray validator
if haystack is an empty array, an exception 'haystack option is mandatory' is thrown
should be exact equality ===




<?php
$t = array();
if ($t == null) echo "null\n"; else echo "not null\n";




this code echoes null




<?php
$t = array();
if ($t === null) echo "null\n"; else echo "not null\n";




this code echoes not null
Update InArrayTest.php

removed unused cache test assets from test suite
Update InArrayTest.php
Update InArrayTest.php

the test testSetEmptyHaystack is not anymore needed as null can't be set 
on the setHaystack function because of the array type needed and empty array 
is possible.
