[windows dev] Tests failing with cargo nextest run

[fdefelici]

On Windows, test executions using cargo nextest run complete with failures.

Some tests fail just when running with parallel execution (running them in isolation complete successfully), due to database locking, like:

• tests::integrations::block_limit_runtime_test
• tests::integrations::bad_contract_tx_rollback

Other consistently fails, due to invalid filesystem path, like:

• util_lib::bloom::test::test_bloom_counter_to_filter
• util_lib::bloom::test::test_bloom_counter_is_invertible_over_iterations

To be investigated the complete set of failing tests and related root cause and understand if could be permanently fixed
