smart-scopes-proxy doesn't use cached list of remote scopes if network is not available

[Paweł Stołowski]

It seems that network failure is not correctly handled where it should be while fetching list of remote scopes, and we attempt to parse empty string -
smart-scopes-proxy.log:

[2014-12-11 14:31:16.212609] INFO: SSRegistry: SmartScopesClient.get_remote_scopes(): Remote scopes:

[2014-12-11 14:31:16.214007] ERROR: SSRegistry: SmartScopesClient.get_remote_scopes() Failed to parse json response from uri: https://dash.ubuntu.com/smartscopes/v2/remote-scopes: unity::ResourceException: Failed to parse json string: * Line 1, Column 1
  Syntax error: value, object or array expected.

[2014-12-11 14:31:16.214467] ERROR: SSRegistry: SSRegistryObject: get_remote_scopes() failed: unity::ResourceException: Failed to parse json string: * Line 1, Column 1
  Syntax error: value, object or array expected.

This causes cached remote-scopes.json to be ignored, and all remote scopes disappear from Manage Dash until network becomes available.

Steps to reproduce:
1) Make sure you see remote scopes in Manage Dash - All.
2) Enable flight mode
3) Reboot the phone
4) Watch /home/phablet/.cache/upstart/smart-scopes-proxy.log
5) Go to Manage Dash - All: NO remote scopes are listed.
