fix tmarshalsegfault depending on execution time (#24153)

Added in #24119, the test checks if every string produced is equal, but
the value of the strings depend on the `now()` timestamp of when they
were produced. 30 of them are produced in a for loop in sequence with
each other, but the first one is set after the data is marshalled into
and unmarshalled from a file. This means the timestamp strings can
differ depending on the execution time and causes this test to be flaky.
Instead we just make 2 strings from the same data and check if they
equal each other.
