One profile can have more ancestors with same submodules

Description of problem:
One profile can have more ancestors with same submodules. It leads to WFLYCTL0212: Duplicate resource [("subsystem" => "subsystem_name")] . Hierarchical composition of profiles was added to AS with EAP7-281 and WFCORE-382

How reproducible:
Always

Steps to Reproduce:

1. get fresh EAP
2. ./domain.sh
3. ./jboss-cli.sh -c
4. /profile=mail-01:add
5. /profile=mail-02:add
6. /profile=mail-01/subsystem=mail:add
7. /profile=mail-02/subsystem=mail:add
8. /profile=default-new:add
9. /profile=default-new:list-add(name=includes, value=mail-01)
10. /profile=default-new:list-add(name=includes, value=mail-02)

Actual results:
No errors.

Expected results:

{
    "outcome" => "failed",
    "failure-description" => {"domain-failure-description" => "WFLYCTL0401: Profile 'mail-01' defines subsystem 'mail' which is also defined in its ancestor profile 'mail-02'. Overriding subsystems is not supported"},
    "rolled-back" => true
}

Workaround:
Add any subsystem to default-new profile:

1. /profile=mail-01:add
2. /profile=mail-02:add
3. /profile=mail-01/subsystem=mail:add
4. /profile=mail-02/subsystem=mail:add
5. /profile=default-new:add
6. /profile=default-new/subsystem=jdr:add
7. /profile=default-new:list-add(name=includes, value=mail-01)
8. /profile=default-new:list-add(name=includes, value=mail-02)
