[ui] duplicated string in message when an env with dvs-plugin is successfully deployed

[Ruslan Khozinov]

Fuel build: 464, 496, 507
dvs-plugin-version: 2.0.4

Steps to reproduce:
1. Deploy environment with plugin (dvs or nsxv)
2. Click at 'Show additional information' on Dashboard

The message:
"
Success
Provision of environment 'test' is done.
Plugin fuel-plugin-vmware-dvs is deployed. Enable to use plugin vmware_dvs for Neutron
Deployment of environment 'test' is done.

Plugin fuel-plugin-vmware-dvs is deployed. Enable to use plugin vmware_dvs for Neutron
"

Firstly, we should remove duplicated string.
Secondly, we should remove this terrible message " Enable to use plugin vmware_dvs for Neutron Deployment of environment 'test' is done. "

The same with resetting:
"
Environment 'env' was successfully reset
Environment 'env' was successfully reset
"
