Deleted Flow in config "magically" shows up after node restart.

A flow that is deleted in config ds, appears after node restart.

Steps to reproduce:

1) start controller with bin/karaf

2) install odl-openflowplugin-flow-services-ui or odl-openflowplugin-flow-services-ui-li

3) enter the "magic" sequence:

3.1) add a flow, like example below or anything you like:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<flow xmlns="urn:opendaylight:flow:inventory">
<hard-timeout>0</hard-timeout>
<idle-timeout>0</idle-timeout>
<priority>2</priority>
<flow-name>flow1</flow-name>
<match>
<ethernet-match>
<ethernet-type>
<type>2048</type>
</ethernet-type>
</ethernet-match>
<ipv4-destination>10.0.10.0/24</ipv4-destination>
</match>
<id>1</id>
<table_id>0</table_id>
<instructions>
<instruction>
<order>0</order>
<apply-actions>
<action>
<output-action>
<output-node-connector>1</output-node-connector>
</output-action>
<order>0</order>
</action>
</apply-actions>
</instruction>
</instructions>
</flow>

3.2) Remove the flow

3.3) Add again the same flow

3.4) Remove again the flow

4) Stop controller (i.e. logout)

5) Start controller bin/karaf

Deleted flow is there in config!
