Fix for regression in open_succeeds_twice and `minimal_writer_examp…

…le` tests (#1667) * Use test-specific temp subfolder to avoid leftovers from previous run Signed-off-by: Michael Orlov <[email protected]> * Address flakiness in TestRosbag2CPPAPI::minimal_writer_example - The `serialized_msg2` is not owning the serialized data after the first call writer.write(serialized_msg2,..). i.e. need to use another message or another API in test for second call to writer.write(msg).
