<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Reset post types and taxonomies before each unit test.
Registering a post type or taxonomy during a unit test causes modifications to
global variables. If the test fails to clean up these globals - either by
neglecting to call _unregister_post_type()/_unregister_taxonomy() at all or by
failing before getting a chance to do so - tests that run later in the suite
can fail, leading to much gnashing of teeth. Wiping all taxonomies and
restoring to the defaults before each test ensures that we always start with a
clean slate.
