Return $this from login() to allow for chaining

I find myself wanting to do $auth->login($user)->issue() instead of multiple lines

@grantholle even though I agree that would be a single line beauty, the login method on other guard drivers don't behave like this.

I guess they return either the user or boolean.

The token issue is the second step, for an already authenticated user.

Since it does not affect very much other stuff, I'll merge it, but I'll keep it open for a while to include this on a next release, to avoid breaking BC.

Thank you!

Also, changed the target branch to develop. master is release only. Thanks

Could you not just use the tap() helper method?

tap($auth)->login($user)->issue();
