fix: prevent race condition between i18next causing translation to fail

[Akarshit]

Resolves #309, #300
Impact: major
Type: bugfix

Issue

One of the flow that was causing this problem was:

1. Before getting shop, we load "en" translations.
2. The page is rendered.
3. Now we get the shop, we again try to load the "en" translation in the same object.
4. Before the object is ready React is re-rendering the components and the translations are all failing.
5. The object loads, but the translations are already empty.

Note this is one possible flow, since the stuff is happening is async more could be possible.

Solution

Don't load the translations again until the language is changed.

Breaking changes

None exptected

Testing

1. Start the platform.
2. Visit admin, refresh the page a bunch of times. Now every-time the correct translations should load.

Just saw the failing lint, will update the code tomorrow.
