Re-activate EtcdDBTest testPutSomethingMoreComplexForSubTreeIntoDSReadItBackAndDelete

[vorburger]

while working on #4 I had to @Ignore the testPutSomethingMoreComplexForSubTreeIntoDSReadItBackAndDelete in EtcdDBTest (all other tests passed) - the goal of this issue is to re-activate it and fix the problem:

java.lang.IllegalArgumentException: Node (urn:opendaylight:params:xml:ns:yang:mdsal:test:binding?revision=2014-07-01)nested-list[{(urn:opendaylight:params:xml:ns:yang:mdsal:test:binding?revision=2014-07-01)name=nested1}] is missing mandatory descendant /(urn:opendaylight:params:xml:ns:yang:mdsal:test:binding?revision=2014-07-01)type

This was (only) on the bertrandlow-PR-5-with-more-fixes branch which I abandoned, forget about this.
