Steps to reproduce

1. Create a Page on a Site where the info.magnolia.livecopy.i18n.LiveCopyI18nContentSupport is configured. (no livecopy slave)
2. Open the Page
3. Log is full of unnecessary spam.

Expected results

> Livecopy does not spam the log

Actual results

example (one of many / more in the log):

> 2021-12-09 18:41:01,621 WARN  info.magnolia.livecopy.jcr.LiveCopyUtils          : Cannot find masterContentIdentifier property for /aurubis-com node
