CCMA 3.2.7 - migrating users related to space erroneously checks users not related to space with duplicate and invalid emails

Issue Summary

Migrating space with 'Migrate users related to the spaces you select to migrate' also check users unrelated to space having duplicate and invalid email address and fails at pre-flight check

Steps to Reproduce

1. User CCMA 3.2.7
2. Create a space S with user A
3. Create user B and user C with invalid and same email address
4. Migrate space S with the option 'Migrate users related to the spaces you select to migrate'
5. CCMA will fail at pre-flight check with invalid and duplicate users B and C

Expected Results

As users B and C are unrelated to Space S, they should not be scanned during the pre-flight check.

Actual Results

Migration fails at pre-flight check reporting invalid and duplicate users which are not related to Space being migrated

Workaround

The current workaround is to use an older version of CCMA by using the dark feature.

1.  Uninstall the current version of CCMA and install 3.2.3 from the following page:
   CCMA All Version
2. Enable the following dark features on the confluence serve, refer to How to add dark-features-in-confluence:
