Merge #15532: Remove sharp edge (uninit member) when using the compiler-generated ctor for BlockFilter

82c3b3f8e07f0572327275841333256fa3e679e3 Remove sharp edge (uninitialized m_filter_type) when using the compiler-generated constructor for BlockFilter (practicalswift)

Pull request description:

  Remove sharp edge (uninitialised member `m_filter_type`) when using the compiler-generated constructor for `BlockFilter`.

  Before (but after added test):

  ```
  $ src/test/test_bitcoin -t blockfilter_tests/blockfilter_basic_test
  Running 1 test case...
  test/blockfilter_tests.cpp(118): error: in "blockfilter_tests/blockfilter_basic_test": check default_ctor_block_filter_1.GetFilterType() == default_ctor_block_filter_2.GetFilterType() has failed [ != ]

  *** 1 failure is detected in the test module "Bitcoin Test Suite"
  ```

  After:

  ```
  $ src/test/test_bitcoin -t blockfilter_tests/blockfilter_basic_test
  Running 1 test case...

  *** No errors detected
  ```
