Fix for replacePlaceholders with ending dot

I noticed that placeholders at the end of a sentence are not matching. 

':causer.name has updated :properties.updatedFields.'

Removing the last dot works, but is not always nice. 

I would suggest changing the regex a little.

Use scoped instances of instead of singletons

See https://laravel.com/docs/8.x/container#binding-scoped.

These are essentially the same thing as `singleton` instances, only difference being that Laravel will make sure that the `scoped` instances get refreshed every request (in Octane) and every job (Horizon).
