Swag: Fail when module contains no package

[LennyPenny]

Describe the bug
When using this with go modules:
If the module only has sub packages and no package itself

$ tree
.
├── a
│ └── a.go
├── b
│ └── b.go
└── go.mod

then swag init will fail.
The error message is:

2019/07/02 16:36:50 execute go list command, exit status 1, stdout:, stderr:can't load package: package gitlab.com/fino/uba: unknown import path "path/to/module": cannot find module providing package path/to/module

Creating a random go file that contains the package , fixes the issue

I think you are using go list on the ./ directory, which causes this

Expected behavior
It should work without a redundant "root" package in the module

Screenshots
If applicable, add screenshots to help explain your problem.

Your swag version
e.g. 1.6.0

Your go version
e.g. 1.12.6

I am running into this with the a module that exists outside of the GOPATH. I notice the command used is just go list -f={{.ImportPath}} but locally that command does not work, the command that does is go list -f={{.ImportPath}} ./...
I believe the change needs to be made in parser.go on line 111 to:
cmd := exec.Command("go", "list", "-f={{.ImportPath}}", "./...")
but I have not dived any deeper for my case.
