Should 'dotnet migrate' respect the "projects" node in global.json?

Steps to reproduce

git clone https://github.com/DustinCampbell/omnisharp-roslyn
git checkout -b migrate-bug
dotnet migrate

Expected behavior

The global.json file is defined like so:

{
  "projects": [
    "src",
    "tests"
  ]
}

My expectation is that dotnet migrate would only attempt to migrate projects in the “src” and “tests” directories.

Actual behavior

The projects in the “test-assets” directory were also modified (which definitely should not be changed!).

Environment data

dotnet --info output:

We should respect the Projects node in global.json and we should respect the projects in your SLN file as well.

We are already respecting the projects in global.json, when you do dotnet migrate global.json.

I will double check that we do that for dotnet migrate solution.sln.

We have a separate bug tracking running dotnet migrate in folder migrated the appropriate artifact.
