Summary:
When dev set the following config, we want stack traces to be printed even if `lowLevel` output is muted (stack traces is output at `lowLevel` for various reasons such as coloring, but semantically it is part of the error output).
```
memlabConfig.muteConfig = {
muteError: false,
muteWarning: false,
muteInfo: true,
muteSuccess: true,
muteLog: true,
muteTable: true,
muteTrace: true,
muteTopLevel: true,
muteHighLevel: true,
muteMidLevel: true,
muteLowLevel: true,
};
memlabConfig.verbose = true;
```
This diff patches the MemLab console output module so that stack traces is still printed when `muteLowLevel` is `true` while `muteError` is `false`.
