Enable DUMMY_LOCALE via "?locale=aa" on URL
Enable DUMMY_LOCALE via "?locale=aa" on URL

The locale coercion function needs to be aware of the dummy locale
("aa") to allow testing using the dummy locale.  So now the following
should work for testing with the dummy locale:

    > yarn intl:dummy
    > ENGINE_URL=https://localhost:8443/ovit-engine yarn start

    Open VM Portal URL with the dummy locale:

        http://localhost:3000?locale=aa
