Duplicated error dump files in stacked tryCatchLog calls

[aryoda]

This code creates two dump files but should create only one:

tryCatchLog(
    tryCatchLog(
      log("a"),
      write.error.dump.file = TRUE),
    write.error.dump.file = TRUE
 )

If the inner tryCatchLog contains an error handler only one dump file will be created (correctly)
so it seams the reason is that unhandled errors bubble up (propagate) and are dumped on each tryCatchLog level.

tryCatchLog(
  tryCatchLog(
    log("a"),
    error = function(e) {
      # do something
    },
    write.error.dump.file = TRUE),
  write.error.dump.file = TRUE
)
