Research public properties/methods in `RequirementsChecker` and hide unneeded

[vjik]

For example, normalizeRequirement() and $result.

Hi vjik, getting the following reminder when running 'php requirements.php' at the console:

Deprecated: Creation of dynamic property Yiisoft\Requirements\RequirementsChecker::$result is deprecated in C:\wamp128\www\invoice\vendor\yiisoft\requirements\src\RequirementsChecker.php on line 67

Any ideas why this is hapenning?

Weird. There is a property defined: https://github.com/yiisoft/requirements/blob/master/src/RequirementsChecker.php#L64

Any ideas why this is hapenning?

It already fixed here: #71.
Try new version 1.1.

Issue from first message is actual.
