 - Add `PII-LAM_CSAGender` to CCAFS Phase II project tags in `input-forms.xml`

+## 2018-04-15

+- While testing an XMLUI patch for [DS-3883](https://jira.duraspace.org/browse/DS-3883) I noticed that there is still some remaining Authority / Solr configuration left that we need to remove:

+2018-04-14 18:55:25,841 ERROR org.dspace.authority.AuthoritySolrServiceImpl @ Authority solr is not correctly configured, check "solr.authority.server" property in the dspace.cfg
+java.lang.NullPointerException
+```
+
+- I assume we need to remove `authority` from the consumers in `dspace/config/dspace.cfg`:
+
+```
+event.dispatcher.default.consumers = authority, versioning, discovery, eperson, harvester, statistics,batchedit, versioningmqm
+```
+
+- I see the same error on DSpace Test so this is definitely a problem
+- After disabling the authority consumer I no longer see the error
+- I merged a pull request to the `5_x-prod` branch to clean that up ([#372](https://github.com/ilri/DSpace/pull/372))
+- File a ticket on DSpace's Jira for the `target="_blank"` security and performance issue ([DS-3891](https://jira.duraspace.org/browse/DS-3891))
