`getUserFromRequest` typing issues

[andreialecu]

It appears that getUserFromRequest allows returning an object that doesn't contain a roles field.

The roles field seems to be hardcoded in other places, and is required. Here's a simple repro:

	type User = { name: string };

	CaslModule.forRoot<Roles, User>({
      getUserFromRequest: (request) => {
        return {
          name: 'test',
        };
      },

This leads to errors further down. Ideally, the signature of getUserFromRequest would verify that a AuthorizableUser<T> is being returned.

try the new version npm i nest-casl@1.4.3

@andreialecu should be good > 1.4.3, I'll close for now, feel free to reopen if needed
