Convert DOM IDs before submitting ActionBroadcastJob

When broadcasting to a target with a suffix, i.e.
```ruby
target: [active_record_instance, :some_attribute]
```

The array will get passed to `ActionView::RecordIdentifier.dom_id`
which turn it into something like:
`"active_record_instance_1234_some_attribute"`.

This works fine when broadcasting synchronously, but because array
gets serialized into a parameter for the `ActionBroadcastJob`, it
ends up forming an illegal target, something like:
`"#<ActiveRecordInstance:0x00000> some_attribute"`

This seems to include a memory address so it should be pretty much
guaranteed that it does not result in any predictable changes to the
DOM.

This behavior difference is a bit confusing and hard to debug.

This change generates the `target` names before serializing the job
parameters, to keep the behavior consistent between the regulater and
`later` methods.

Behavior for existing applications may or may not change, depending on
whether people expect this not to work.
