## **Description**

This PR aims to remove redundant e2e tests, specifically those in the
quarantine folder. The two tests that will be removed in this PR is:
- `import-nft.failing.js`:
- We already have test steps to import an NFT:
https://github.com/MetaMask/metamask-mobile/blob/main/e2e/specs/assets/nft-details.spec.js#L49#L52
   - `send-to-contact.failing.js`
        - We have multiple e2e tests that send funds to an address.
