fix: ensure that connect_devices is called

[jacopoabramo]

ophyd-async requires a call to device.connect() to ensure the signal backends are properly connected.

Right now this is just a patch to ensure that for prototyping this works, but I'm evaluating if this is something that should be delegated to the presenter layer.

The reason is that I originally intended to support methods such as standby(), connect(), disconnect() in order to manage the device connection to the application so that the user may decide to keep the application alive but disconnect the device or put it in a standby mode if available.
