Fix: don't load social login if no env var is set

[compojoom]

What it solves

Resolves #
We should be able to start the app by just providing the infura token and nothing else.

How this PR fixes it

If we haven't specified any social_wallet_options, the social login is not enabled.

How to test it

1. Clone the PR
2. Create an .env file with just

NEXT_PUBLIC_INFURA_TOKEN=YOUR_KEY
NEXT_PUBLIC_SAFE_APPS_INFURA_TOKEN=YOUR_KEY

You shouldn't get an error now when you run yarn dev

📦 Next.js Bundle Analysis for safe-wallet-web

This analysis was generated by the Next.js Bundle Analysis action. 🤖

⚠️ Global Bundle Size Increased

Page	Size (compressed)
global	1.03 MB (🟡 +1.07 KB)

Details

The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

If you want further insight into what is behind the changes, give @next/bundle-analyzer a try!
