Configure fails when new packages are updated

This frequently happens when I use cabal sandbox add-source. However it also happens when I simply create a sandboxed module, add some undefined code, change my cabal file with a new dependency, and try to C-c C-l. It fails with an error like:

```
Starting inferior `cabal repl' process using cabal ...
-> :set prompt "\4"
-> Prelude.putStrLn ""
-> :set -v1
<- ./mylib.cabal has been changed. Re-configuring with most recently used

<- options. If this fails, please run configure manually.

<- Resolving dependencies...

<- Configuring mylib-0.1.0.0...

<- cabal: T
<- he following package dependencies were requested
--dependency='base=base-4.7.0.1-e4b74d27ad8c8987c63abc42a80e7335'
however the given installed package instance does not exist.
```

I have to exit out of the current project and then restart it or it will keep failing at the configure step. It seems like settings are remembered and it's depending on specific installations hashes?
