dotnet build on a test project won't rebuild referenced project when there are source changes.

[joperezr]

Steps to reproduce

1.- Create a Library project with a method
2.- Create a test project that references the Library project's method
3.- run dotnet restore on both projects and dotnet build on both projects.
4.- Make a change on Library project's method to make the test fail.
5.- build and run the test again. <-- Test project will still pass

Expected behavior

Test project should fail because Library project should be automatically rebuilt

Actual behavior

Test run succeeds because it is still using the old version of the Library.

This is working for me right now even without msbuild.
