[Bug] mapSync artifact causes iLEAPP to hang on encrypted iOS backup

While running iLEAPP on a decrypted iOS backup (originally encrypted), the mapSync plugin caused the process to hang indefinitely. When I re-ran iLEAPP excluding the mapSync artifact, it completed successfully.

**Steps to Reproduce:**
- Decrypt encrypted iOS backup using [jfarley248/iTunes_Backup_Reader](https://github.com/jfarley248/iTunes_Backup_Reader).
- Run iLEAPP on the decrypted output folder with all artifacts selected.
- The run gets stuck on mapSync and never completes.

**Expected behaviour:**
The tool should either complete processing or provide an error message rather than hanging.

**Observed behavior:**
The process stays stuck at mapSync indefinitely (no further logs, CPU usage stays constant).

**Environment:**
OS: MacOS 15.5 (24F74)
Python version: 3.12

**Command used:**
`python ileapp.py -t itunes -i "/path/to/decrypted_backup" -o /path/to/output`

**Log file:**
I’ve attached the _Script_Logs folder from the run that got stuck.
