templates/homepage: Fix counters display when storage is empty

This is a simple fix for the counters display in the webapp homepage.

When the storage is empty (for instance after booting the docker env), the /api/1/stat/counters endpoint returns an empty dict.

So handle that corner case to avoid a JavaScript error when homepage is loading.

Could you add a test for this? (eg. using Cypress to mock calls to the counter API)
