Fail utils method in UIView (CLUViewRecordableAdditions) if arguments are invalid

[Geek-1001]

Description

We need to fail some utils method in UIView (CLUViewRecordableAdditions) if input arguments are invalid.

For example:

- (NSDictionary *)clue_fontPropertyDictionaryForFont:(UIFont *)font {
    NSMutableDictionary *fontDictionary = [[NSMutableDictionary alloc] init];
    if (font) {
        [fontDictionary clue_setValidObject:font.familyName forKey:@"familyName"];
        [fontDictionary clue_setValidObject:font.fontName forKey:@"fontName"];
        [fontDictionary setObject:@(font.pointSize) forKey:@"pointSize"];
        [fontDictionary setObject:@(font.lineHeight) forKey:@"lineHeight"];
    }
    return fontDictionary;
}

If user will pass invalid font – this method will return empty dictionary. But if font is invalid, we don't need font dictionary at all.
Here are some utils method from UIView (CLUViewRecordableAdditions) which I think needs to be fixed (return nil if input argument is invalid)

• -clue_fontPropertyDictionaryForFont:
• -clue_attributedTextPropertyDictionaryForAttributedString:
• -clue_colorPropertyDictionaryForColor:

Note : We need to check where those method used and ensure that we won't pass invalid object into dictionary for example.

Problem

We don't need empty dictionary if input argument is invalid.
