When trying to get the im_status of several partners, if one of them
does not exist, it will return an error.
To reproduce the error:
1. Go to Contacts
2. Open a contact
3. Action > Delete
4. Wait max 50 seconds
=> A Missing Record message is displayed. The im_status RPC includes the
deleted partner's identifier and the server looks for it.
Now, the server skips the missing identifiers.
