Reviewed by Ryosuke Niwa.

Source/WebCore:

The content-scheme handler specification requires that it is SecurityError if the length of
scheme isn't five characters at least, including 'web+' prefix. Thus, we need to check the length
of scheme on the 'web+' scheme.

Spec: http://www.whatwg.org/specs/web-apps/current-work/#custom-handlers

No new tests, just modify existing tests.

(WebCore::verifyProtocolHandlerScheme):

LayoutTests:

Add a test case to check if the length of 'web+' is five characters at least.
