Test Plan:

• checkout master cashtab
• npm start and ensure pre-alias cashtabCache is loaded
• arc patch this diff
• npm start, upon cashtab startup verify the console log is displaying invalid cashtabCache detected, missing params initialized from currency.defaultCashtabCache and ensure post-alias cashtabCache contains the new aliasCache object as well as retaining the existing tokenInfoById object
• double check ALL existing tokens in tokenInfoById have been retained
• refresh cashtab and ensure console log is displaying valid cashtabCache detected
• npm test
