fix SELECT name FROM ENTITY

Summary

Fixes #130 (closed)

Focus

The actual fix is only a if(id>99) because the error occured when the result set contained some of the special entities (which are usually hidden to users).

Test Environment

Tests in caosdb-pyinttest!4 (merged)

Manual testing: checkout this branch in deploy and search FIND ENTITY or SELECT something FROM ENTITY.
