Wrong bundles in EntityFieldQueryTestCase

Found out when working on the field info cache optimization in #1040790: _field_info_collate_fields() memory usage :

EntityFieldQueryTestCase::setup() does not properly declare the bundles it adds on test field types.
In order to have the bundles appear in entity_get_info(), and in the current state of the field_test.module, the function to call is field_test_create_bundle() - which takes care of calling field_attach_create_bundle().

Not critical for the current state of Entity API / Field API, but working on bundles that are not listed in entity_get_info() is not recommended.

Given the strictly test-internal nature of this, and probable low amount of reviewers for that, I'll be bold and push this directly to RTBC. Feel free to scold :-)
