When a line contains only a dash it cannot safely be assumed that
it contains a nested list or an embedded mapping. If the next line
starts with a dash at the same indentation, the current line's item
is to be treated as `null`.
[SwiftmailerBridge] Bump allowed versions of swiftmailer

Current version of Swiftmailer is 5.2.1, while (previously to this commit)
the version installed by composer was 5.0.3.

This is rather important, since 5.2.1 closes a security issue that 5.0.3 is
vulnarable to (https://github.com/swiftmailer/swiftmailer/issues/494).

I think FormBuilder::getIterator() should resolve children before makes an iterator because it seems to be used in same purpose with FormBuilder::all().
What do you think?

[Form][Validator] All index items after children are to be considered grand-children when resolving ViolationPath

#### Possible BC Break
The old behavior had unit test cases specifically testing the case of a grand-children form. However, this behavior is not documented anywhere and the fix seems to have no adverse effects on form validation. `Symfony\Component\Form\FormInterface` implements `ArrayAccess`, therefore, semantically speaking, `children[direct_child].children[grand_children]` and `children[direct_child][grand_children]` are equivalent. `offsetGet` is expected to fetch an element from `children`. I do not see why both were not considered equivalent when resolving the ViolationPath.

This commit will indeed change how some errors are mapped. However since the old mapping is (in my opinion) a bug...
