Global error handler - default handler

[mwear]

We recently added a global error handler in #1514. The default handler uses a ConsoleLogger at LogLevel.Error. This has the unfortunate side effect of spamming standard out during tests. Should we consider making the default global error handler a no-op instead?

my 3 cents: I would be in favor of having a noop as a default.

I think it would make sense in the test suite, however i believe we need to report errors for end user by default
