This PR fixes a bug in the sawtooth_validator::journal::commit_store::CommitStore's get_batch_by_transaction method, which heretofore returned the first batch that does not contain the provided transaction_id argument without any error.

The equivalent Python method calls the Rust method via FFI:

# validator/sawtooth_validator/journal/block_store.py

def get_batch_by_transaction(self, transaction_id):
        """
        Check to see if the requested transaction_id is in the current chain.
        If so, find the batch that has the transaction referenced by the
        transaction_id and return the batch. This is done by finding the block
        and searching for the batch.

        :param transaction_id (string): The id of the transaction that is being
            requested.
        :return:
        The batch that has the transaction.
        """
        payload = self._get_data_by_id(
            transaction_id, 'commit_store_get_batch_by_transaction')

        batch = Batch()
        batch.ParseFromString(payload)

        return batch

Here's commit_store_get_batch_by_transaction, which is called in the snippet above and calls get_batch_by_transaction:

//! validator/src/journal/commit_store_ffi.rs

#[no_mangle]
pub unsafe extern "C" fn commit_store_get_batch_by_transaction(
    commit_store: *mut c_void,
    transaction_id: *const c_char,
    batch_ptr: *mut *const u8,
    batch_len: *mut usize,
    batch_cap: *mut usize,
) -> ErrorCode {
    check_null!(commit_store, transaction_id);

    match deref_cstr(transaction_id) {
        Ok(transaction_id) => {
            match (*(commit_store as *mut CommitStore)).get_batch_by_transaction(transaction_id) {
                Ok(batch) => return_batch(batch, batch_ptr, batch_len, batch_cap),
                Err(err) => map_database_error(err),
            }
        }
        Err(err) => err,
    }
}

Would it also work to just remove the "!" before "batch"? (If so, it would keep the performance of using any instead of all.)

Rebase should resolve the jenkins build error (it should be excluded).
