Joe McGill 788bb093f2 Media: Remove alt fallbacks to improve accessibility.
This removes the fallbacks in `wp_get_attachment_image()` and in
`wp.media.string.props` which attempt to generate an `alt` value
from the image caption or title if an `alt` attribute isn't explicitly
set.

This allows for image HTML to be generated that contains an empty `alt`
value, i.e., `alt=""` which is much preferable for screen readers than
reading redundant content in the case of a caption, or when reading the
image title, which is often generated from the filename and not helpful
as `alt` text.

Props odie2, joedolson, rianrietveld, afercia, iamjolly, joemcgill.
Fixes #34635.

The short version:

1. Create a clean MySQL database and user.  DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.

2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.

3. $ svn up

4. Run the tests from the "trunk" directory:
   To execute a particular test:
      $ phpunit tests/phpunit/tests/test_case.php
   To execute all tests:
      $ phpunit

Notes:

Test cases live in the 'tests' subdirectory.  All files in that directory will be included by default.  Extend the WP_UnitTestCase class to ensure your test is run.

phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run.  This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs.  Pure unit tests may be used also, of course.

Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.

phpunit is intended to run at the command line, not via a web server.
