Conan: [workspaces] Assertion and weird output

[theodelrieu]

Hello,

I'm using the new workspaces feature in 1.13.1 on a side project, and an assertion gets raised:

File "/Users/theo/Library/Python/3.6/lib/python/site-packages/conans/client/output.py", line 119, in write
    assert self.scope != "virtual", "printing with scope==virtual"
AssertionError: printing with scope==virtual

Additionally, there are a lot of redundant build requirement outputs like the following:

mgs_meta/0.1.0@mgs/testing: Applying build-requirement: mgs_cmake/0.1.0@mgs/testing
mgs_meta/0.1.0@mgs/testing: Applying build-requirement: mgs_test_helpers/0.1.0@mgs/testing

Please @memsharded take a look. I managed to reproduce it easily but looks far from being obvious what is the issue or issues here. Something with the build requires looks very messed up and I really don't understand the "virtual" node assert.

Working on it, confirmed it is a bug, and it is an extremely complicated one. Will update as soon as possible.

Confirmed fixed with the planned fix for 1.13.2

1.13.2 Released!
