Description

Updating from v1.1.0 to v1.2.0 may cause panic because of the following line:

dbresolver/clauses.go

Line 49 in 691098d

 stmt.DB.Callback().Query().Get("gorm:db_resolver")(stmt.DB) 

Get("gorm:db_resolver") would return nil if db_resolver is not set up correctly, which would cause "runtime error: invalid memory address or nil pointer dereference".

Fixed that.
