Stripping empty, optional field device_one_time_keys_count during initial sync breaks Element Android encryption #10456
Description
#10214 (released in Synapse v1.38.0) removes optional keys from /sync responses if they're an empty value. This can cause the current Element Android release to fail to set up encryption properly after an initial sync, which breaks encryption support. This leads to many unable to decrypt errors, which have started popping up again in reports (i.e element-hq/element-android#1721).
The plan is for Synapse to introduce this field again to fix the current version of Element Android, while allowing some time for a fixed Element Android to be released and for people to update.
