Wrong file name for WP_Automatic_Updater

[ocean90]

It's class-wp-automatic-upgrader.php but should be class-wp-automatic-updater.php.

Introduced in [37409].

1. svn mv src/wp-admin/includes/class-wp-automatic-upgrader.php src/wp-admin/includes/class-wp-automatic-updater.php
2. Apply 37628.patch​

[DrewAPicture]

@ocean90 37628.diff​ re-copies class-wp-upgrader.php at [37342] to class-wp-automatic-updater.php, the contents of which I then replaced with the contents of class-wp-automatic-upgrader.php and then deleted the latter.

The difference between this and 37628.patch​ is that we theoretically retain many of the blame records.

1.

 bash
$ svn cp -r 37342 https://develop.svn.wordpress.org/trunk/src/wp-admin/includes/class-wp-upgrader.php src/wp-admin/includes/class-wp-automatic-updater.php
A         src/wp-admin/includes/class-wp-automatic-updater.php

2.

Manually replaced -updater.php contents with current -upgrader.php code

3.

 bash
$ svn rm src/wp-admin/includes/class-wp-automatic-upgrader.php 
D         src/wp-admin/includes/class-wp-automatic-upgrader.php

@ocean90 In retrospect, doing the mv should retain the history as long as we don't move it to a different directory.

In 38242:

Upgrader: Rename class-wp-automatic-upgrader.php to class-wp-automatic-updater.php.

The class is named WP_Automatic_Updater not WP_Automatic_Upgrader like all the other upgrader classes.

Introduced in [37409].
See #37628.

Props DrewAPicture for review.
Fixes #37628.
