Title: Fixed invalid delimiter used in preg_quote to check field value.

Use '/' instead of '$/' because '$' is the standard character to escape. If use '$/' as delimiter it's impossible to check fields value against date strings as ''25/10/2012".
Error that you can get without this fix is "PHP Warning: preg_match(): Unknown modifier '1' in vendor/behat/mink/src/Behat/Mink/WebAssert.php on line 474"
