server connection state is confused and/or lost after suspend and resume

After resuming from a suspend, the previous behavior was to reconnect to the owncloud server. Or, instruct the app to reconnect.

With 16.04, the app claims that there is no connection to the owncloud url. Trying to log out of the server seems to force confuse the app (it thinks it's logged in but with no connection). Several cycles of logging in and out gives the same behavior: No connection to Owncloud URL.

There is no way to reconnect without killing the app and restarting.

The failure is reliable: it happens every time.

Steps to reproduce

    Open owncloud
    Suspend the computer
    Owncloud doesn't reconnect properly
