Use in-memory sqlite3 databases in all tests instead of TemporaryDirectory from stdlib or the tmp_path pytest fixture.
Also convert tests/integration/dcr/test_dcrdata.py to the pytest format.
The diff is somewhat messed up by the large de-indented blocks, unfortunately.
NOTE: originally I converted the tests to use the pytest's tmpdir feature, but then realized that using in-memory databases would be simpler and make tests faster.
