(Go) unexpected argument at index 2 with two items in GOPATH

Bug Report

Current Behavior I have two items in the GOPATH variable, which has the benefit, that packages downloaded via go get are placed in the path of the first item and my own packages belong to the second item. You can read more about this here.

You'll see the following when opening the shell.

Welcome to fish, the friendly interactive shell
[: unexpected argument at index 2: '/Users/danieltrautmann/Development/Projects'

~ ➜

go env

~ ➜ go env | grep GOPATH
GOPATH="/Users/danieltrautmann/Development/Go:/Users/danieltrautmann/Development/Projects"

variable content

~ ➜ echo $GOPATH
/Users/danieltrautmann/Development/Go /Users/danieltrautmann/Development/Projects

Expected Behavior I'd expect no error message at all.

Relevant Fish Configuration

_~/.config/fish/conf.d/04go.fish

set -gx GOPATH $HOME/Development/Go $HOME/Development/Projects
set -gx GO111MODULE off

_~/.config/fish/conf.d/99prompt.fish

set SPACEFISH_PROMPT_ORDER exit_code kubecontext golang pyenv git dir char

Environment

Spacefish version: 2.2.2
Fish version: 3.0.1
Fish plugin manager: fisher
Terminal emulator: iTerm
Operating system: OSX 10.14.3

Possible Solution I figured out that [ -n $GOPATH ] in ~/.config/fish/functions/__sf_section_golang.fish is causing this and fixed it by replacing it with [ (count $GOPATH) -gt 0 ].

Now the prompt looks like the following.

~ ➜ cd ~/Development/Go/src/github.com/spf13/cobra/

🐹 v1.11.5 on  master in cobra ➜ cd ~/Development/Projects/src/github.com/danieltrautmann/httpstat/

🐹 v1.11.5 on  csv-output [!?] in httpstat ➜
