Adding actionview in Rakefile to run test [ci skip]

and create versions

/cc @tenderlove

Dropped deprecated option `:restrict` for `:dependent` in associations

Removed support for deprecated `delete_sql` in associations.

Removed support for deprecated `insert_sql` in associations.

use extract_options!

Removed support for deprecated finder sql

Removed support for deprecated `counter_sql`

Removing not useful test related to reflect_on_all_associations

update test names in testing guide [ci-skip]

The comment in the test pretty much summarizes the issue.
`FIXME these assertions bust a lot`

Adding any type of association in class `Firm` will break this test.

I removed some deprecated stuff and this test failed.

I do not think this test provides any useful value. First of all who
counted last that 39 is the right number of associations.

Secondly there are a large number of tests which depend on reflection
returning right information about associations. Those tests will start
failing if there is a bug in the code.

Remove deprecated `Date#to_time_in_current_zone`

Remove deprecated `config.whiny_nils`
