Add CurrentTenant class that can be resolved from container

[AlexVanderbist]

Allows for things like this:

use Spatie\Multitenancy\Models\Contracts\CurrentTenant;

Route::get('/current-tenant', function (CurrentTenant $currentTenant) {
    return $currentTenant; // returns the current Tenant model
});

Looking very good, thanks!

Just one question.

[freekmurze]

What happens if there is no current tenant?

[AlexVanderbist]

Good point, currently it'll new up a new Tenant instance but I'll change it to be null

[AlexVanderbist]

Hm, same issue exists for the currentTenant. I'll make both null

[AlexVanderbist]

Too many issues:

• wanted to throw an exception when resolving a currentTenant when there is no current tenant
• can't hook into resolving a key that doesn't exist in the container
• laravel will automatically create a new Tenant when trying to resolve CurrentTenant::class, even though it's literally bound to null 😠

Gonna close this for now due to the above issues.
