Stack fails to build "mutually recursive" packages

### General summary/comments (optional)

I have a two-package project, where the library in package `two` depends on the library in package `one`.

However, there's also an executable component in package `one` that depends on library `two`. For some reason, plan construction fails, even when I try to build single components.
### Steps to reproduce
1. `git clone git@github.com:mitchellwrosen/stack-issue-1.git`
2. `stack build`
### Expected

Build succeeds
### Actual

Build fails with:

```
While constructing the build plan, the following exceptions were encountered:

Plan construction failed.
```
