Taxonomy hooks backwards

The test bot hasn't run yet, but this looks like an obvious fix. Committed.

Let's write some tests for that.

Tests for taxonomy terms hooks are there, but the way taxonomy_test.module implement those hooks, doesn't cover bugs like this one.

The attached patch update the taxonomy_test.module, to fix the implementations of taxonomy terms hooks and simplify them.

Instead of having one-to-many relationship of term-antonyms, is simplest to have one-to-one relationship, it's just a test module.

A few tabs crept into the patch:

-  }
+function taxonomy_test_get_antonym($tid) {
+	return db_select('taxonomy_term_antonym', 'ta')
+	    ->fields('ta', array('name'))
+	    ->condition('tid', $tid)
+	    ->execute()
+	  ->fetchField();
 }

Fixed.

still some tabs here, and the fetchField() should be indented the same as the other chained methods. Otherwise looks RTBC.

+function taxonomy_test_get_antonym($tid) {
+  return db_select('taxonomy_term_antonym', 'ta')
+      ->fields('ta', array('name'))
+      ->condition('tid', $tid)
+      ->execute()
+    ->fetchField();
 }

Excellent! Committed to HEAD.
