Flaky fuzz tests for filtered outer SortMergeJoin #12359

Description

@korowa

Describe the bug

After replacing the filter for join fuzz tests with the selective one (that doesn't return 100% of input rows), it turned out that following tests may periodically fail for HashJoin vs SortMergeJoin cases:

  • test_left_join_1k_filtered
  • test_right_join_1k_filtered
  • test_full_join_1k_filtered

To Reproduce

To reproduce this one should add JoinTestType::HjSmj to mentioned above test cases and run them (likely a couple of times)

Expected behavior

SMJ and HJ should return equal resultsets for these test cases
