  • Change trytoShow's to not use raw string
  • Add an enrichedErrorMessage on Run, so to only handle the first exception

Some of the changes from #16685.

This looks like a good core of uncontroversial (I think) yet highly beneficial changes to land.

Perhaps some of the rest of #16685 and/or #16593 could eventually land as separate followup PRs.

Having a same-named enrichement will cause the original to be called
if/when explicit nulls is switched off - which leads to the original
method to be called, meaning an NPE will be thrown.

So, instead, move all the functionality as an extension method, so we
don't need mangled names.
