Remove scopeguard

The scopeguard crate was being used for its `defer_on_unwind` macro.
The problem was that it runs even if the runtime was already panicking.
There aren't any changes to the macro which could have fixed this.
I instead wrote my own function to check for a specific panicking closure.
