Add operation of a multi value attribute via patch action fails on path values with selection filters

[eziv-ptc]

Description:
PathcOperationUtil.doPatchAdd "loses" the value for the selection filter and hence the entire patch action fails. This happens when adding a new attribute. When replacing an attribute value (via "add" or "replace") - the old selection filter is used instead of the new one (from the request).

Affected Product Version:
3.3.33 and above

Steps to reproduce:

1. Create a single user
2. Update a multi value attribute for that user with a patch request that contains a selection filter. For example:

{
    "schemas": [
        "urn:ietf:params:scim:api:messages:2.0:PatchOp"
    ],
    "Operations": [
        {
            "op": "Add",
            "path": "emails[type eq \"work\"].value",
            "value": "john_doe@foo.com"
        }
   ]
}
