bash debug trap doesn't work with shell integration for multi-word functions

[meganrogge]

1. add trap "echo Hello" debug to your .bash_profile with shell integration disabled -> Hello is echoed
2. enable shell integration and create a bash terminal
3. 🐛 Hello is not echoed

this is because cut' ' -f3 uses ' ' as the delimiter and -f3 gives only the 3rd field that results from that. As shown here, to get the full thing for this case, you'd need -f4 as well. I don't think this is a good approach as a result and we should revert to cutting off trap and DEBUG to preserve the whole function that should be trapped

@meganrogge I'm not sure this case is particularly important since traps are typically always set to functions?

[meganrogge]

I don't think we should hope that is the case. They can be strings that are quite complicated

Ok let's try to fix it, I also probably broke #150850 with the change, I verified the Starship prompt issue is fixed though.

Should be easy to fix. I can make a PR after testing

Spent several hours trying to get this to work to no avail.
