Fix test-log/EquivalenceOfLoggingAndTraversal

The test has been marked as intermittently failing since 2011 and since that "code-creation" event signature has changed a bit. I updated the parser in the test but that revealed another issue: "code-creation" events with type 'Script' didn't match functions with type 'LazyCompile' retrieved during the heap traversal because the later had name " :1:1" which didn't match the script's name.
