fix(PROJ-44): SNIPPET via SELECT statt CALL SNIPPETS (Go MySQL-Treiber-Kompatibilitaet)

Browse Source 
CALL SNIPPETS liefert einen anderen MySQL-Pakettyp als SELECT, den der
Go-Treiber (go-sql-driver/mysql) mit "malformed packet" ablehnt.
SELECT SNIPPET(text, query) FROM table ist die korrekte Alternative
fuer Manticore 25.
