Summary:
We have two application: applicationA and applicationZ.
applicationA has a registered schema "applicationA" and is installed on device.
applicationZ has in it's .plist a whitelist entry in LSApplicationQueriesSchemes "applicationA".

Still when I do [[UIApplication sharedApplication] canOpenURL:url], with url = [NSURL URLWithString:@"applicationA://"], it return NO with this log in device console:

Jan  1 01:02:18 iPad-41-Air-v100 applicationZ S(UIKit)[374] <Notice>: -canOpenURL: failed for URL: "applicationA://" - error: "This app is not allowed to query for scheme applicationa"

As you see i'm querying "applicationA" and it's not allowing me to query "applicationa" (lowercase).

I've never seen nowhere in documentation the enforcing of lowercase in schema, is it now a case or is it a bug?

Steps to Reproduce:
1. first app register a schema in camelCase;
2. second app in it's .plist a whitelist entry in LSApplicationQueriesSchemes in camelCase;
3. second app try to query canOpenURL with url in camelCase that will result in NO even if it must be YES.

Expected Results:
Expecting canOpenURL to return YES.

Actual Results:
Result of canOpenURL return NO.
