Create new schema definition without assignee field.
We are removing assignee functionality. The assignee field will be
removed from Change. Therefore we make the getter always return
NO_ASSIGNEE.
The previous changes in the stack of changes removing assignee
functionality. Already removed all usages of Assignee field (read and
write) RestApi, Querying, Reading from and setting to Notedb. Meaning
that assignee is not populated for both the older version of index
(because it's not read from notedb and can't be changed via rest) and
for the new version of index (because we remove it from schema)
