[JS] Getter function for singular message fields

[mirzazadeh]

Getter function for singular message fields in javascript returns "undefined" when the field is not set. This is not consistent with the behavior of getter function for such fields in all other languages.

This is very inconvenient and is a source of bugs because programmer has always check for undefined values for nested messages (imagine multi levels of nested submessages). It can be fixed by introducing new getter function like msg.GetFooOrDefault().

This is a reasonable feature request that we have internally.
