When a user from a LDAP delegated directory is added and/or removed to a group, no information is added to the audit log

Summary

When a user is added to a group, an information is added to the audit log. This is not the case when the user is from a Ldap delegated user directory.

Steps to Reproduce

1. Create a directory as Ldap delegated
2. Create a user in this directory
3. Add (or remove) the user to a group from the Internal User directory (or any other, e.g. a Ldap delegated one).

Expected Results

A line with the GroupMembershipCreatedEvent is added to the atlassian-bitbucket-audit.log when the user is added to the group.

For example:

192.168.56.1 | GroupMembershipCreatedEvent | admin_user | 1478836011970 | group | {"entity":"ldap_user","membership":"GROUP_USER"} | @XRXBANx886x3890x0 | i8rrld

A line with the GroupMembershipDeletedEvent is added to the atlassian-bitbucket-audit.log when the user is deleted from the group.

For example:

192.168.56.1 | GroupMembershipDeletedEvent | admin_user | 1478836580427 | group | {"entity":"ldap_user","membership":"GROUP_USER"} | @XRXBANx896x3953x0 | i8rrld

Actual Results

No line is added to the audit log.
