Clay Management Toolbar taglib uses incorrect locale.
Steps to reproduce:
1) Open portal as anonymous user, http://localhost:8080 or your host:port
2) Change language to Arabic using language prefix, like this: http://llocalhost:8080/ar/web/guest
3) Log In with account which has English as default language (test)
4) Go to Content&Data -> Web Content (or any other place where we have Management Toolbar)
Expected result: Management Toolbar rendered in English, as any other part of portal since English is default language for the user
Actual result: Management Toolbar is rendered in Arabic (see screenshot)
