John Newbery 5448a1471d [tests] don't override __init__() in individual tests
Almost all test scripts currently need to override the __init__()
method. When they do that they need to call into super().__init__() as
the base class does some generic initialization.

This commit makes the base class __init__() call into set_test_params()
method. Individual test cases can override set_test_params() to setup
their test parameters.

"""Test the zapwallettxes functionality.
- start two bitcoind nodes
- create two transactions on node 0 - one is confirmed and one is unconfirmed.
- restart node 0 and verify that both the confirmed and the unconfirmed
transactions are still available.
- restart node 0 with zapwallettxes and persistmempool, and verify that both
the confirmed and the unconfirmed transactions are still available.
- restart node 0 with just zapwallettxed and verify that the confirmed
transactions are still available, but that the unconfirmed transaction has
been zapped.
