The genesis block can't be retrieved

[AlexITC]

We can't retrieve the genesis block from the API

Expected behavior

The following call returns the genesis block: https://xsnexplorer.io/api/blocks/00000c822abdbb23e28f79a49d29b41429737c6c7e15df40d1b1f1b35907ae34

Actual behavior

The block not found error is retrieved while calling: https://xsnexplorer.io/api/blocks/00000c822abdbb23e28f79a49d29b41429737c6c7e15df40d1b1f1b35907ae34

Insights

Turns out that the issue occurs because there are no rewards on this block while the explorer expects that every block has a reward (even if it is 0).
