f-name-query -> dev

# Summary

Fix for #51

See  caosdb-mysqlbackend!13  for more information.

# Focus

The backend-api has changed and most of the changes just replace any usage of the obsolete `entities.name` column be an equivalent SQL using the `name_data` table.

The statements are independent of each other and can be reviewed piece by piece. I added a docstring for all sql statements in question.

Luckily, most of the server's interactions with the backend stays untouched, because the server uses higher level procedures for most things, which are changed in caosdb-mysqlbackend!13 
 

See #11.

FIX: Shadowing sensitive properties during logging.

See merge request caosdb/caosdb-server!43

Actually this was already mostly implemented before, but the bug was not closed.

For issue #68.
