`toTyped` ignores default values in class

Given
```
class Bird {
name: String = "DEFAULT"
colloquialName: String = name
}
```
evaluating
```
new Dynamic { name = "Pigeon" }.toTyped(Bird)
```
results in
```
new Bird {
name = "Pigeon"
colloquialName = "DEFAULT" // <- unexpected
}
```

The same holds for the `toTyped` definition on `Map`, so the following produces the same result:
```
new Dynamic { name = "Pigeon" }.toMap().toTyped(Bird)
```

No source file or test is named in the issue. Reproduce the examples for Dynamic.toTyped and Map.toTyped, then trace their handling of class defaults; done means both conversions preserve the supplied name while deriving colloquialName from it rather than using the declared default.
