Cannot publish a project that is referenced by other projects in the workspace

[fsoikin]

When checking dependencies, spago publish checks dependencies of all packages in the workspace, not just the one being published.

The culprit line is:

spago/src/Spago/Command/Publish.purs

Line 120 in 5407217

let allCoreDependencies = Fetch.toAllDependencies $ dependencies <#> _ { test = Map.empty }

It smooshes all dependencies in a single bucket before checking them.

Repro

./spago.yaml

package: 
  name: project-a
  publish: ...
workspace:
  ...

./b/spago.yaml

package: 
  name: project-b
  dependencies:
    - project-a

Try to publish:

> spago publish -p project-a

Your package "project-a" is not ready for publishing yet, encountered 1 error:

✘ Some of the packages you specified as `extraPackages` do not point to the Registry.
To be able to publish a package to the registry, all of its dependencies have to be packages registered on the Registry.
Please replace the following packages with versions that are present in the Registry:
