The assertion error for 'incude(object, propName)' is cryptic when 'propName' is a string

When you make a mistake and use assert.include instead of assert.property to assert that an object has a specific property (e.g. assert.include({ foo: 'bar' }, 'foo');), the error message is very unclear:

> chai.assert.include({ foo: 'bar' }, 'foo')

AssertionError: object tested must be an array, a map, an object, a set, a string, or a weakset, but object given

Can we do something to indicate clearly that this combination of arguments (an object + a string) is not possible for assert.include?
