* Make MessageBag constructor behaviour consistent with `add`

Addresses laravel/ideas#56 and the (long-closed) laravel#13196.

This change in constructor behaviour aims to bring consistency with the
public `add` method on the MessageBag class, which would prevent
duplicate values in any given MessageBag's key.

* update test to show consistency of behaviour

current Blade functionality allows the user to define a default value if the first value is not set.

`{{ $name or 'Andrew' }}`

This feature was added in an early version of Laravel to be a shorthand for

`isset($name) ? $name : 'Andrew'`

PHP7 has introduced the null coalesce operator (`??`) which performs this exact functionality.

`$name ?? 'Andrew'`

While the 'or' feature was good when it was needed, it could produce unexpected results when the characters 'or' appeared anywhere in the Blade expression.  This was solved with extensive regex, but was still somewhat error prone.

Now that Laravel requires PHP 7.1, we can utilize the null coalesce operator and remove the 'or' feature. User upgrade process will be a find and replace, and the number of characters will be identical.

```
{{ $name or 'Andrew' }}
{{ $name ?? 'Andrew' }}
```

Currently, jobs scheduled via console scheduling can not specify a connection to dispatch that job onto. They can specify a queue.
This PR adds an optional connection parameter to the end of the job function.
