Fixes #297

[bytestream]

Description

Laravel validation converts * to __asterisk__ in Laravel 6+ (laravel/framework#31257).

helpers.js relies on [*] to parse those wildcard rules:

regexFromWildcard: function(name) {
      var nameParts = name.split("[*]");

Todo:

• Find a solution for Laravel 5.6 - 5.8 or bump the minimum version to 6.0+
• Add tests
