Changing category, as the generated errors point to the merchant backend, not the exchange.

529cf92..828cd52 cleans up the /proposal logic improving error messages and proposal generation (nicer style), but also fixing a previously improperly done (lack of transaction scope) pre-flight test for an already existing order. Now the constraint check is simply done by relying on the DB constraint, and then we just run the 'get_order' to confirm that the hard error was indeed the constraint violation and not something else. So in the common case the result should be much faster, and we properly use the transactions now.

It is _not_ clear that this was the bug, though.

84d4c87..9b683b2 improves logging in case this bug reappears.

Unassigning, as I am not sure how to reproduce (loaded the DB, but would need a matching frontend setup to generate failing transactions). Hopefully the new logging will help diagnose this if this is still an issue.
