quoted_table_name with abstract models

[matiasleidemer]

When updating to Rails 4, I've encountered a nasty error message:

ActiveRecord::StatementInvalid:
PG::SyntaxError: ERROR:  zero-length delimited identifier at or near """"
LINE 1: ..._table".* FROM "my_table"   ORDER BY ""."rgt" d...
                                                                    ^
: SELECT  "my_table".* FROM "my_table" ORDER BY ""."rgt" desc LIMIT 1

The model implementing nested_set is quite simple:

class MyModel < ActiveRecor::Base
  self.abstract_class = true

  acts_as_nested_set
end

Everything was fine with Rails 3.2, but when updating to Rails 4, it started to break. After some source digging I've seen this: https://github.com/collectiveidea/awesome_nested_set/blob/master/lib/awesome_nested_set/model.rb#L17

The delegation of quoted_table_name to self isn't working anymore (at least with abstract models) and I guess it may be related with this issue rails/rails#10658.

Defining self.quoted_table_named in my abstract model seems to solve the problem, though it feels a little hacky, and may not be the perfect solution for everybody facing this problem.

Not sure if this is an awesome_nested_set issue (I really don't think so) but I think it's important to point that out.

Actually this is happening with Rails 3.2 too, not only Rails 4, my mistake...

@matiasleidemer Do you have a spec drawn up that can demonstrate this issue? I think I have a fix, but I want to make sure I'm fixing the right thing.
