Feature request: Add a way to remove warning in config

[MLefebvreICO]

Hi there,

Like the title says, we would like to remove the warnings when the SourceMap position is not find for a trace, because it adds so much lines for nothing to me.

It could be an option we could set in karma's conf file.

In addition, the Karma formatError -function doesn't get triggered for these logs, making for an oppressive batch of error messages unless you set logging to errors only, or use different types of sourcemaps.

Do you have an example? There's not a single log.warn statement in the source code, which would be the source of warnings.
