Display both last_error() and last_trace()

This saves me a click

I can't reproduce the snapshots locally due to unrelated problems so someone else will have to finish this off 😞

I feel like that's too much information to present by default, as well as a too long line. To me it already feels like too much as it is.

Alternative ideas:

• Support options(rlang_backtrace_on_error = "reminder_trace") as you suggested on Slack.
• Support double click alt-behaviour in hyperlinks. You'd double click to show the full trace.
