CreateGuildRoleParams is identical to ModifyGuildRoleParams, so just use
the latter when creating new roles.

The GuildHelper.CreateRoleAsync() was sending 2 requests to create a role. One to create the role, and one to modify the role that was created. This can be done in one request. So i have moved it to a single request to lower the amount of requests send to the api. This will also solve issue #1451.

* Add event and method
