fix: collection nft error

[aspnxdd]

Fixes #218

Changes

• This error fixes the issue described in #218 . Fetching the NFTs threw an error which was set to the setError state, then the error hid the cm config. If there is a problem fetching the NFTs it should not affect the CM config.
• Also changed how the collection NFT is rendered. Having 2 states for the collection NFT is a good idea (boolean and data itself), sometimes the NFT collection exists but it is empty, I added some fallback texts to show an empty image and hide the solscan link in case it exists but it is empty.
• Fixed solscan link in NftCard, an extra ? was causing issues in the url.
• Stop infinite loading if no nfts are found.
