Yarn workspace does not propagate flags

[thevojacek]

When using yarn workspaces with run command, flags are not passes into executed command.

How to reproduce:

yarn workspace test_workspace run start -- \
  serverURL="hello" \
  awsAccessKey="world"

package.json file contents.

{
  "scripts":
  {
    "start": "node script.js""
  }
}

Current behavior:

Flags are not passed into the running script.

Expected behavior:

Flags should be passed.

Environment

Node: 12.13.1
Yarn: 1.21.1
OS: macOS 10.14.6

confirmed against v1.21.1.

I'll try to see what's up with it. It's a bit tricky because yarn runs child process yarn runs child process node scripts.js so the flags have to get passed through a couple places.

@thevojacek as a workaround, if you remove the -- then the parameters are passed correctly.
It looks like yarn trims off args after -- for some commands, including workspace.

Thank you for investigation!
