Sergey Biryukov b698f8f475 Posts, Post Types: Correct the check for non-existing post in get_post_permalink().
The function was erroneously calling `is_wp_error()` on the result of a `get_post()` call, which returns `null` on failure, and never returns a `WP_Error` object.

Previously, passing a non-existing post ID to the function would result in a home URL being returned and a few `Attempt to read property "post_type, post_name, hierarchical..." on null` PHP warnings.

This commit ensures `get_post_permalink()` returns `false` on failure, which brings parity with `get_permalink()`.

Includes a unit test to confirm the correct behavior.

Follow-up to [12923], [13023], [32606].

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.
