reporter: Eliminate undefined behavior in SaveErrorReport

Browse source 
The optionals are unconditionally dereferenced when setting the custom
error text, and in a few cases this function is called using the default
value of the optionals.

This means we'd be dereferencing uninitialized storage.

Since they're used unconditionally, we can use value_or to set a default
when storage is uninitialized.
