403 Error on Murano Status page

[Ekaterina Chernova]

Steps To Reproduce:
1. Deploy simple environment with Fuel 5.0.1 and Murano, Neutron GRE, nonHA: 1 controller and 1 compute.
2. Open Horizon dashboard and navigate to Murano > Application Catalog > Statistics

Observed Result:
Error with 403 code.
How it looks on UI: http://s30.postimg.org/gvwyzipen/Screenshot_from_2014_07_29_19_52_03.png

Thee reason of this error in the incorrect logic of page with statistics collection. This page create new session for all environemts in specific tenant and in the result if we have at least one environment in deploing state (we can't create new session for environment in deploing state) we will have this error.
