Wrong trigger number logged when expression crashes during load

[brunchboy]

Describe the bug
When re-creating the trigger window, if a setup expression for a trigger whose index is not 1 throws an exception, the dialog which appears displays the correct trigger number, but the log file entry always reports the failure occurred for Trigger 1

To Reproduce
Steps to reproduce the behavior:

1. Set up a trigger numbered 2 or higher with a setup expression that will crash (e.g. trying to send to a nonexistent MIDI device).
2. Save the triggers.
3. Load the triggers (or quit and re-launch BLT).
4. See the dialog reports the correct trigger number, but the log file does not.

Expected behavior
Both should report the correct trigger number.
