Title: Kern 2413 Tag migrator won't process all tags

Go to Solr directly so we can be more efficient and fetch only the tag field, which is all we need. Use rows and start params to loop over results until we run out of rows to process. Also fix a crash that occured when JCR has no /tags node (ie a clean install of v1.1).
