Init not works on Windows (eternal loop)

[dissipative]

What happened?

go run scripts/gqlgen.go init
lasts forever

What did you expect?

Behavior as described here: https://gqlgen.com/getting-started-dep/

Minimal graphql.schema and models to reproduce

Schema and models are not used, just gqlgen.go script as in instructions

versions

gqlgen version = 0.9.1
go version = go1.12.4 windows/amd64
GOPATH = C:\Users\Username\Develop\go

Actually, the problem is in ImportPathForDir function in internal/code/imports.go path.
There is an infinite loop at 64 line: firstly it checks for the go.mod file, then it tries to find absolute package path and just doing comparison to "/".
I have not tried it in Unix-like systems, but in Windows 10 with dep (and without go mod) installation the loop will never stop because after several cycles variable modDir is became equal to "C:\".
Reference to the problem:

gqlgen/internal/code/imports.go
