app crashes are not recorded in the log file when using the --log option

[nikhilsaraf]

Describe the bug

If the bot was to crash with a panic then it is not logged to the file when using the --log option

Expected behavior

I think the correct behavior in this situation is for the bot to log these errors to the file as well so we can fully depend on the log files

Frequency

The frequency is: Always

Steps To Reproduce

Here are the steps to reproduce the issue (see attachments in section below):

1. Create a strategy with a panic operation to force it to crash
2. Start the bot using the --log flag
3. the bot will crash and the standard out will display the panic but the log file will not.

Possible Solution

This bug can be fixed by catching any panics at the highest level and logging that before exiting.
