Update trial page misleading text.

• Update the frontend misleading issue text per #120 (closed)

Available solutions:

1. Directly update the entry then run

$ rake gettext:regenerate

to update the current *.po files, which can be adapted since this modifies files under root/locales that breaks JH mirror strategy.

2. Hard code

We can add a file under JH directory which overrides the view interface that user sees, in this case we can simply remove the part s('Country') with desired text, but this is not a good solution since it's not flexible, and it also breaks the upstream tests.

3. More elegant solution

Implement JH only translation service(Since JH should only support 3 different type of languages).

Also we need to mark the part Country/Region as partial in order not to break the tests.
