go debugging (delve) not launching properly

[sbromberger]

Summary

Even with the latest bugfix for the unwrap error, delve is still not working in helix. The debugger is terminated upon target selection.

Reproduction Steps

I tried this:

1. hx myfile.go
2. <space>gb to set breakpoint
3. l to select target
4. select binary target, full path

I expected this to happen:
delve to start and debugging session enabled

Instead, this happened:
Terminated debugging session and disconnected debugger. message appears below statusline

Try to select the source target if you want to select a source file.

I've just checked that it works on the master branch.

But if delve, for example, fails to compile the source code or launch a binary then the helix debugger section will be leaved in the error state and you need to manually terminate it using t key.
