Intent only import in lu will pull unrelated contents

[feich-ms]

Versions

4.12.0-rc0

Describe the bug

Reported by composer here microsoft/BotFramework-Composer#5756 (comment). Intent import in lu will pull unrelated contents. Consider below scenarios:

common.en-us.lu:

# Greeting
- hi
- hello

root.en-us.lu:

[Common](common.en-us.lu)

# MyIntent
- test 1
- test 2

test.en-us.lu

# Test
- [MyIntent](root.en-us.lu#MyIntent)

The generated luis file for test.en-us.lu with luis:convert command will pull everything from common.en-us.lu, which is not expected.

To Reproduce

Steps to reproduce the behavior:

1. Create above lu files
2. Use bf luis:convert -i test.en-us.lu to convert lu to luis
3. You will see intent and utterances in common.en-us.lu are added into the generated luis json file

Expected behavior

Only MyIntent is pulled
