fix: remove error when rendering template with language not set to English

[dodumosu]

Setting a browser language to a non-English language will cause the application to error out.

Can you explain what kind of error you receive? If your PR is merged, it would prevent the display of the menu items in any other language other than English. Ideally, the menu items should be marked as translatable and rendered in English if there's no available string in the chosen language, unless I'm missing something.

The specific exception is a TypeError with the message: "unhashable type: _LazyString". To reproduce:

1. Compile language catalogs
2. Set browser language to any supported language, eg French
3. Open app in browser (preferably with debug mode turned on)

The reason the error comes up is because the items I'm removing the translation helper from are all already strings marked for translation in the Python source code. Marking them again for translation in the template is what causes the error.

Please see this issue and the PR that fixes it.

You are absolutely right. I've approved the PR. We would need to also confirm that all the menu item names are adequately marked for translation.
