Solve "Error: Could not establish connection. Receiving end does not exist."

In MV3, this error comes up in various contexts. It seems harmless but as noise it would be good to minimize it. It mostly happens in the onActivated listener as far as I can tell.

1. When trying to activate on chrome:// tabs.
2. When trying to activate tabs that existed before the current version of the extension was installed. (this is tracked at Doesn't work on existing tabs when enabled immediately after install or update #36)

The former could be fixed with a check in the handler, the latter probably needs to be solved as part of a larger fix of handling stale tabs when the extension is updated.

From https://stackoverflow.com/questions/10994324/chrome-extension-content-script-re-injection-after-upgrade-or-install there is an example regex:

if (tab.url.match(/(chrome|chrome-extension):\/\//gi)) {
        continue;
      }
