MOD on a large static group takes too long if substring index is present.

Issue Description
If the substring index is configured for the group membership attribute ( member or uniqueMember ),
the removal of a member from a large static group is pretty slow.

Package Version and Platform:

Platform: Red Hat Enterprise Linux Server release 7.8 Beta (Maipo)
Package and version: 389-ds-base-1.3.10.1-5.el7.tkt51166.x86_64

Steps to Reproduce

Create the substring index for the membership attribute.
Add a large static group.
Delete a member from the group.
The MOD operation to remove the value is too slow.

Expected results
Fast MOD operation.

@jchapma it looks a good candidate for previous releases. If it applies to older releases would you backport it to those releases ? thanks
