FIND REFERENCES: subquery + class filter

[DeividasJackus]

It would be great if FIND REFERENCES would allow to specify both a sub-query AND a class filter:

FIND REFERENCES (SELECT FROM V) V

Error: com.orientechnologies.orient.core.sql.OCommandSQLParsingException: Error on parsing command at position #30: Class list must be contained in []

I am not sure if there's even a workaround for this right now (without issuing several queries) as FIND REFERENCES results cannot be used in another query (#4267)

This is an example to use it with select:

select from ( select expand( referredBy ) from ( find references (select from V limit 1) ) ) where @class = 'HasCategory'
