Root cause analysis: dedupePaths crash

The dedupePaths function in workspace-config-files has always assumed that when a config writer exists, there will be at least one extending config file generated with component paths. This assumption breaks with the new react-starters v2.0.0.

Old starters (v1.x): Created sample React components (button, app, etc.) that used teambit.react/react-env. That env generates extending config files for all its writers (typescript, eslint, prettier), so dedupePaths always had non-empty paths.

New starters (v2.0.0): Only creates a custom env component (envs/my-react-env) using the base teambit.envs/env. That base env registers an eslint config writer, but generateExtendingFile() returns undefined for it — so the extending config files map is empty. dedupePaths is then called with no component paths, but "." (root dir) is still added as a possible directory. Math.max(...[]) evaluates to -Infinity, causing the crash.

The fix adds an early return in dedupePaths when there are no component paths to process.
