1.0.0-alpha2

• Skip tests if no solr backend.

Also adds clean-up after test is run, because drupal tests do this for the db not solr.

• Add method to be used in https://github.com/localgovdrupal/localgov_search/pull/49/commits/18380fe27e6ae113cbaf460131f2e37ae3cd4aa2

This, without a cache clear, ensures the items are indexed for the test.
