Don't show full trace on routing errors

Since dbcbbcf2bc58e8971672b143d1c52c0244e33f26 the full trace is shown by default on routing errors.
While this is a nice feature to have, it does take the attention off the
routes table in the routing view. I think this is what most of the people
look for in this page.

Added an exception to the default trace switching rule to remove that
noise.
