Never loads click preview again if first tried offline

[Sebastien Bacher]

Using a bq 4.5 on rc-proposed r76
- boot with flight mode enabled
- hold a tap on an icon to see its click preview

-> you get an empty screen bouncing forever

- go back to the apps view
- turn off flight mode/enable some data connection
- try to open a click preview view

-> you still get the empty screen and never ending bouncing

the unity8-dash.log has those errors

"Caught an error from preview(): unity::scopes::TimeoutException: Request timed out after 500 milliseconds (endpoint = ipc:///run/user/32011/zmq/priv/clickscope, op = debug_mode)"

We don't do anything special connectivity wise on unity8, i've checked and we call scope.preview() again the second time so if it's not working (that i checked it does not) it must be some of the lower layers getting confused.

Pinging some people about it.

I can reproduce it. When it happens then click scope gets "stuck" and runs indefinitely (scoperunner doesn't get killed) and doesn't respond to search / preview requests anymore. Attached is the stacktrace of all threads when it is in such state. By the look of things it is stuck on a conditional variable in pay::Package::is_refundable().

  * Depend on upstart instead of upstart-bin which is a dummy
    transitional package.

  [ Rodney Dawes ]
  * Sign the requests to CPI by default. Add tests to ensure signing is
    requested. (LP: #1483866)
