Incorrect warning "no files matching any of the following globs"

[graup]

Describe the bug

When running storybook build, this warning is printed:

WARN We found no files matching any of the following globs:
WARN
WARN ../src/stories/**/*.stories.(js|mdx)

However, everything works! Stories are loaded properly. So, it seems the warning is just incorrect.

To Reproduce

Version: next @ 4b7c1a4

Steps to reproduce the behavior:

1. cd examples/vue-kitchen-sink
2. yarn storybook

When testing the migration of a Vue-based monorepo (Yarn/Lerna) project based on feedback in #10817, I am also running into this same warning:

WARN We found no files matching any of the following globs:
WARN
WARN ../components/**/*.stories.(js|mdx)
WARN ../lib/**/*.stories.mdx

However, none of my stories are loading :/

All @storybook dependencies are on 6.0.0-beta.8.

I think @yannbf was working on a fix for this?

Hey everyone, this is a duplicate of #10772. A fix is on the way, it just needs to be further discussed! 🙆‍♀️
