Merge bitcoin#17140: test: Fix bug in blockfilter_index_tests.

f59bbb6 test: Fix bug in blockfilter_index_tests. (Jim Posen)

Pull request description:

  The test case tests a chain reorganization, however the two chains were generated in the same manner and thus produced the same blocks.

  This issue was [pointed out](bitcoin#14121 (comment)) by MarcoFalke.
