Re: [presentation-api] PresentationReceiver: rename getConnection() and getConnections()

I agree with the following:
- if the connection goes to ```terminated``` state, it's removed from 
```connections```
- the page can learn about the removal by listening to connection's 
```onstatechange``` and checking against the ```terminated``` state
- ```disconnected``` connections should stay in ```connections``` as 
the page will receive ```onstatechange``` with the state set to 
```connected``` so ```onsessionavailable``` would be redundant
