 Blocks: Add more unit test covering edge cases for Block Hooks

 These two new unit tests document how Block Hooks behave with
 `first_child` and `last_child` relative positions. The hooked blocks will
 only get inserted in the case where the parent block has at least one
 child block present. While it seems like a limitation, in practice, it's
 hard to think of a case where the template would use a parent block
 without its children. It's more likely to happen with patterns in general,
 but in the case of patterns wired with the block theme, it also seems
 unlikely. The reasoning here is that out of the box, the block theme
 should produce a fully functional and valid HTML.

 Props ockham.
