node: print repeating error to the node log

[nullun]

Original comment in: #6376

I was looking through the PR and noticed this is the only use of the newly imported package above ("github.com/labstack/gommon/log" on line 32). I'm just wondering if this was intentional?

Summary

It looked like an error was being sent to the wrong place. I test it and couldn't see the error message, but this PR places it into the log file.

Test Plan

I reduced the ticker to 2 * time.Second and misconfigured a local node. It correctly repeated the error message.

nullun@local demonet % tail -f rootdir/node1/node.log | grep P2PHybridMode

Thank you for the fix, auto-importer error that we did not catch.
