Every tests/test_*.py file provides an

    if __name__ == "__main__":
        unittest.main(...)

entrypoint so it can be run directly, except test_ssti.py and
test_xpath.py. Running either of those directly produced no output and
executed none of its tests; they only ran under `unittest discover`.

Add the missing entrypoint to both so they behave like the rest of the
suite. No test logic changed (62 and 48 tests respectively still pass).

…lts (sqlmapproject#2503) (sqlmapproject#6146)

A scan covering multiple targets inside a single API task (crawl,
'-m' bulk file, forms) ran every target through one StdDbOut keyed by
the single taskid, so _storeData()'s COMPLETE branch deleted each
earlier target's TARGET/TECHNIQUES rows - /scan/<id>/data returned
only the last target's results.

Mirror the --report-json fix for sqlmapproject#6123: controller.start() now sets
kb.reportTaskId per target for API scans too, StdDbOut.write() keys
data rows '<taskid>-<n>' per target, and scan_data() folds the
per-target rows back into the task's flat result in target order.
Single-target scans keep the exact same response shape.

Regression tests in tests/test_api.py (TestStdDbOutMultiTarget,
TestScanDataMultiTarget).
