The Tool doesn't support custom User model

[vladles]

I want to use custom default User model for Laravel Nova, For Example "NovaUser"

If we look at Role Model from current lib we can look that we have relationships without $table arg, and BelongToMany relationships requested "nova_user_role" table in my case.

I have 2 option:

1. Hardcode $table for relationships methods,
2. Customize migrations
