When rearranging account between HDs, the subdomains' DocumentRoot (in httpd.conf) is reset to main domain DocumentRoot.

How to reproduce:

1. Login at WHM
2. Click on Rearrange account
3. Select the account
4. Select the appropriate partition/HD and proceed
5. Check the httpd.conf for subdomains in that account

Plz check and add it in bugzilla.
