Fix referencing wrong aliases while joining tables of has many through
association
While joining table of has_many :through association, ActiveRecord will
use the actual table name instead of through-join alias. It results with
a wrong SQL and exception is raised. This only happens when calculation
methods like #count is called.
This issue is affecting Rails 4.1.x and 4.2.x as well.
