Add back block tests removed from partial refund

[jewei1997]

Describe your changes and provide context

We originally removed some block tests because they were failing due to us removing the full refund of unused gas (https://github.com/sei-protocol/sei-chain/pull/1871/files#diff-0adc342d2882ffb81750cb8734fb7ab5c0a7393082b452370b3aacff3df49777R37-R39). However, we've reverted that change, so adding back these tests.
