EventIndex: Handle invalid m.room.redaction events correctly.

Browse Source 
Clients might send invalid redaction events, such events will not have a
valid redacts field containing the event id of the associated event that
was redacted.

Skip such events instead of ending up looping over the checkpoint
forever.
