Allow authentication header to not have to specify 'token=' key.

Fixes: https://github.com/rails/rails/issues/17108.
Correct test description for large integer test
Allow habtm class_name option to be consistent with other associations
document_root_element need to be public
Use GitHub, not my local fork :sweat_smile:
Generate new applications with the right rails-dom-testing version
Force table creation in tests

If something causes the teardown block to not get run (errors,
interrupting test runs), we have to manually delete them, which is a
pain.
rm `reorder_bind_params`

Arel handles this for us automatically. Updated tests, as BindParam is
no longer a subclass of SqlLiteral. We should remove the second argument
to substitute_at entirely, as it's no longer used
Remove the unused second argument to `substitute_at`

Oh hey, we got to remove some code because of that!
[PERF] Speed up integer type casting from DB

We don't have the check the range when the value is coming from the DB, so
override type_cast_from_database to short-circuit the extra work.

type_cast_from_database (small)  3437507.5 (±29.2%) i/s -   14223135 in   4.996973s
type_cast_from_database (large)  3158588.7 (±28.3%) i/s -   13265628 in   4.992121s
type_cast (small)                 481984.8 (±14.2%) i/s -    2352012 in   5.005694s
type_cast (large)                 477331.8 (±14.2%) i/s -    2332824 in   5.012365s

Comparison:
type_cast_from_database (small):  3437507.5 i/s
type_cast_from_database (large):  3158588.7 i/s - 1.09x slower
type_cast (small):                 481984.8 i/s - 7.13x slower
type_cast (large):                 477331.8 i/s - 7.20x slower

The difference is huge but the absolute gain is quite small. That being said
this is a hotspot and it showed up on the radar when benchmarking discourse.
:nail_care: Put escape clause first, keeps @sgrif happy :grin:

Revert "[PERF] Speed up integer type casting from DB"

This reverts commit 6f7910a and 52c70d4.

Query params are type cased through the same method, so this approach doesn't work.
