MDEV-7922 - ERROR 1939 (HY000): Engine PERFORMANCE_SCHEMA failed to discover table

Performance schema discovery fails if connection has no active database set.

This happened due to restriction in SQL parser: table name with no database name is ambiguous in such case.

Fixed by temporary substitution of default database with being discovered table database.
