hack for getting CLL into history of CLLSLL

correction made from comment by @averyniceday (to use full URI strings to avoid the .endsWith() potential ambiguity)

I have deployed the latest code to : http://dashi-dev.cbio.mskcc.org:8080/sheridan-oncotree/#/home

• the main wepage shows "CLL" in the history for CLLSLL node in all version (stable, development, candidate)
• the api shows history "SLL,CLL" in versions
  • http://dashi-dev.cbio.mskcc.org:8080/sheridan-oncotree/api/tumor_types.txt?version=oncotree_2018_06_01
  • http://dashi-dev.cbio.mskcc.org:8080/sheridan-oncotree/api/tumor_types.txt?version=oncotree_2018_06_15
• the api shows no history for node SLL or CLL in previous versions (when they were separate nodes)
