Update relations after every decryption attempt (#2387)
* Update relations after every decryption attempt
If an event is encrypted the aggregation cannot pick up the relation types.
Before this change there was exactly one aggregation retry after decryption.
If the events are being decrypted afterwards (for example on restore
from key backup) the aggregation was not aware of that.
This change adds relation updates after every decryption event if there
has been a decryption error.
