Update recover method of NFT module to validate NFT attributes array

[Incede]

Expected behavior

NFT store data value should be validated for schema related errors after decoding

Actual behavior

• The recover function of the NFT module does not call validator.validate on the storeValue variable after decoding the value
• The call to codec.decode does not validate astring’s length.

Steps to reproduce

Check the recover method of NFT module
