Generated Go code produces name collisions on imports

If two modules have the same name, the produced go code will not compile.

For example:

import (
  "github.com/sample/project/common"
  "github.com/different/thing/common"
)

In go the final component (commons) is used as the name so there is a collision.

This can be fixed by aliasing the modules

import (
  common_1 "github.com/sample/project/common"
  common_2 "github.com/different/thing/common"
)
