Summary:
When using an NSDataDetector with the NSTextCheckingTypePhoneNumber type included, it will (seemingly incorrectly) detect the text "phone number" before a valid phone number.

Steps to Reproduce:
NSError *error = nil;
NSDataDetector *dataDetector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingTypePhoneNumber
                                                               error:&error];

NSArray *stringsToTest = @[
                           @"testing phone number 0123 4567891",
                           @"testing some other number 0123 4567892",
                           @"phone number 0123 4567893",
                           @"blah blah 0123 4567894",
                           @"testing telephone number 0123 4567895"
                           ];

for (NSString *string in stringsToTest)
{
    [dataDetector enumerateMatchesInString:string
                                   options:0
                                     range:NSMakeRange(0, string.length)
                                usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop) {
                                    NSLog(@"%@", result.phoneNumber);
                                }];
}

Expected Results:
I'd expect the following numbers to be detected and be the sole content of result.phoneNumber:
0123 4567891
0123 4567892
0123 4567893
0123 4567894
0123 4567895

Actual Results:
Instead the NSLog call prints out the following, not in log 1 and 3 the text "phone number" before the actual number:
