This is useful when we need to do some work associated to `Current.reset`
but that work depends on the values of the current attributes themselves.
This cannot be done in the supported `resets` callback because when the
block is executed, CurrentAttributes's instance has already been reset.
For symmetry, `after_reset` is defined as alias of `resets`.
Since `CurrentAttributesTest` changed the global time zone, it is
necessary to restore the original value after changing the test.
The reproduction step:
```
./bin/test -w --seed 5549 test/current_attributes_test.rb test/core_ext/date_ext_test.rb
```
* Add ActiveSupport::CurrentAttributes to provide a thread-isolated attributes singleton
* Need to require first
* Move stubs into test namespace.
Thus they won't conflict with other Current and Person stubs.
* End of the line for you, whitespace!
* Support super in attribute methods.
Define instance level accessors in an included module such that
`super` in an overriden accessor works, akin to Active Model.
* Spare users the manual require.
Follow the example of concerns, autoload in the top level Active Support file.
* Add bidelegation support
* Rename #expose to #set. Simpler, clearer
* Automatically reset every instance.
Skips the need for users to actively embed something that resets
their CurrentAttributes instances.
* Fix test name; add tangible name value when blank.
* Try to ensure we run after a request as well.
* Delegate all missing methods to the instance
This allows regular `delegate` to serve, so we don't need bidelegate.
* Properly test resetting after execution cycle.
Also remove the stale puts debugging.
* Update documentation to match new autoreset
