Fixing username for invited users

[2ndkauboy]

I am using your great program to invite members to our slack team. One new member reported, that the name they provided into the form is used as the first name in slack. I also found the code which sets this value: https://github.com/vluzrmos/lumen-slackin/blob/master/app/Services/SlackTeamService.php#L50

In the form validation you enforce the user to enter two word: https://github.com/vluzrmos/lumen-slackin/blob/master/app/Services/SlackTeamService.php#L50

I would suggest that you only ask for a username, only for the first name or add another separate field for the last name (so the form would than have three fields).

Thanks for your suggestion!

As soon as possible I will do that change.
