Fix delegated property resolve on number literals and proper types

There is no need to update type of delegate expression if it's already
 resolved correctly (doesn't include non-proper types). In almost all
 cases it was fine except number literals as there we didn't box
 expression in backend and got problems at bytecode verification stage
