Count flag is broken in runtime command action list

### Expected Behaviour

aio runtime action list -c=2
... 2 actions listed

### Actual Behaviour

› Error: failed to list the actions: the requested resource does not exist. (404 Not Found)
› specify --verbose flag for more information

### Reproduce Scenario (including but not limited to)

#### Sample Code that illustrates the problem

#### Logs taken while reproducing problem

Start by locating the runtime action list command and its -c/--count option, then reproduce the reported command: aio runtime action list -c=2. Trace why requesting a count produces the 404 error; done means the command lists two actions instead of failing.
