Lookup the class at runtime, not when the association is built

Trying to lookup the parent class when the association is being built
runs the risk of generating uninitialized constant errors because
classes haven't been fully defined yet. To work around this we look up
the class at runtime through the `association` method.

Fixes #10197.

This fixes issue #10066
Added testcase for #10067 and a CHANGELOG entry about this change.
Use DatabaseTasks.fixtures_path instead of FIXTURES_PATH in db.rake

This will allow to set fixtures path in global config easier, it should
be not needed to use FIXTURES_PATH every time user wants to load
fixtures.
Add some documentation to ActiveRecord::Tasks::DatabaseTasks

This is a public class, which could be used directly in order to allow
easier database management. Now it also contains settings, which will be
used by databases.rake.
Don't require Rails.env in order to use AR::Tasks::DatabaseTasks
