Known issue in v6: Uncomfortable error info of Union validation

[yuhr]

As for error reporting, current implementation of Union is somewhat incomplete, for example:

console.log(Union(String, Number, Record({ test: Boolean })).validate({ test: new Date() }));

Then we get:

{
    success: false,
    code: 'TYPE_INCORRECT',
    message: 'Expected string | number | { test: boolean; }, but was object'
}

This is not very helpful. Error reporting algorithm of Union (and also maybe Intersect) seems non-trivial, so I need to investigate how this can be resolved. This issue should be considered as a bug, because above result is just unintentional and incorrect, and we're going to treat bugfixes for this as non-breaking changes.
