Evaluator.visitObjComp doesn't propagate context correctly

[Danstahr]

I wasn't yet able to fully root cause the issue but I derived a minimal example

main.jsonnet

local lib = import "libbroken.libsonnet";

{
  base:: {}
}
+ lib.foo()

libbroken.libsonnet

{
  foo()::
    {
      local global = self,

      [iterParam]: global.base {
        foo: iterParam
      }
      for iterParam in ["foo"]
    },
}

The issue seems to be specific to how the for loop (triggering visitObjComp) is handled. The output is generated properly when the lib code is replaced by

libworking.libsonnet

{
  foo()::
    {
      local global = self,

      foo: global.base {
        foo: "bar"
      }
    },
}

It also generates properly if the global variable is omitted and self is used directly.

Interesting bug! I dug into this and have submitted a fix at #358

Thanks a lot for taking a look Josh!
