Refactor: use tx utils from testenv in chain crate

- import testenv crate in chain crate
- replace all macros and fns in the following
tests with import from testenv crate
    - tests/test_indexed_tx_graph
    - tests/test_keychain_txout_index
    - tests/test_local_chain
    - tests/test_tx_graph
    - tests/test_tx_graph_conflicts
