Pavel Yaskevich 43d83bb461 [BuilderTransform] All if sequences without else should call buildOptional

In cases like:

```
if (...) {
  <body>
} else if (...) {
  <body>
} else if (...) {
  <body>
}
```

Each branch should end with `buildOptional` wrapping `buildEither`
because there is no covering unconditional `else` in the sequence:

```
var $__builder: <<Type>>

if (...) {
  $__builder = buildOptional(.some(buildEither(...)))
} else {
  if (...) {
    $__builder = buildOptional(.some(buildEither(...)))
  } else {
    if (...) {
      $__builder = buildOptional(.some(buildEither(...)))
    } else {
      $__builder = buildOptional(.none)
    }
  }
}
```
