test_update_existing_leaf()

Documentation for tests/mpt/test_storage_trie_structure.py::test_update_existing_leaf@ffe48572.

Generate fixtures for these test cases for Bogota with:

fill -v tests/mpt/test_storage_trie_structure.py::test_update_existing_leaf --fork Bogota

Overwrite the only leaf; the value changes, the shape does not.

pre: leaf(64) = 1 post: leaf(64) = 2
