Fix for JAMES-1815: Copy potentially immutable list to allow modifications

> Crash when reading domainlist via JMX
> -------------------------------------
>
> Key: JAMES-1815
> URL: https://issues.apache.org/jira/browse/JAMES-1815
> Project: James Server
> Issue Type: Bug
> Components: JMX
> Affects Versions: 3.0.0-beta5
> Reporter: Tobias Fleig
>
> Reading the list of domains via JMX from:
> ObjectName: "org.apache.james:type=component,name=domainlist", Attribute
> "Domains"
> crashes with:
> java.lang.UnsupportedOperationException
> at
> com.google.common.collect.ImmutableCollection.add(ImmutableCollection.java:96)
> at
> org.apache.james.domainlist.lib.AbstractDomainList.getDomains(AbstractDomainList.java:131)
> at
> org.apache.james.domainlist.lib.DomainListManagement.getDomains(DomainListManagement.java:69)
> at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
> Some subclasses (JPADomainList, HBaseDomainList, MemoryDomainList) return an
> ImmutableList in getDomainListInternal(). This list is then modified by
> getDomains() in AbstractDomainList, which causes the crash above.
> We will supply a patch/pull request.
