SaveQueue failures log errors to console without configurable control

[Prinsn]

There may be configuration to this, but the mixin for SaveQueuing in v2 appears to forcibly log all errors, and some of our errors returned are "error pages" from C# server.

This causes the entire HTML to be logged, despite our Angular error handlers taking care of the error.

The code, as it appears in the executing source, did not appear to have a configurable option, it will always log every error that passes through it.
