In this PR:
We fixed the issue with volatileGet precompile function upon calling it with key that doesnt exist.
It returns an err, however, it also reverts the whole execution with OutOfGas (gas_used =18158513697557840303)
To avoid such an issue and still be able to handle a non-existing key from the smart contract side:
1- Instead of reverting with an error, we return a status and a value. The status would mark if the key exists or not.
If the key exists, the value will be set accordingly. If not, it will return 0 bytes array with a failure status (false)
2- Added unit tests for existing and non-existing keys
