* In one of the previous PRs for ConciseView, System.Exception was incorrectly added to the typenames handled by the ErrorRecord formatting. This results in just Exception objects written to the console to not be rendered since the ErrorRecord formatting didn't handle this situation. Fix is to remove the line to add that type putting it back to how it was previously.
* Also made the handling of ErrorRecord a bit more robust just in case Exception.Message doesn't exist nor a Message property.
ConciseView shows MyCommand as the prefix to the error message, but for a scriptblock, MyCommand is the whole scriptblock. Fix is to use CategoryInfo.Activity if available first. Also handle case where it's a script function by seeing if it's a command and showing MyCommand in that case rather than the Activity.
