Implement "get initial values" and "get all values" for form data

[rikukissa]

Problem number 1

This seems like a side-effect of us improperly supplying the form without some initial values. We need to write a function that comes up with proper initial values for inputs

'applicant.firstname': ""
'applicant.surname': ""
'applicant.dob': ?
'applicant.image': ?

Ideas

• Force countries to define initial values for all inputs OR alternatively make input components export their initial values easily for our logic to use
  • For some inputs it might not be even possible to assign a default value. "FILE" or "DATE" for instance? Or maybe the default value is null.
  • If you decide to define export const initialValue = "" or similar for the input components, you can do this as addition in the component files in the components package or by creating new wrapper components in packages/client/src/v2-events for each input. We might want to add an export function toString(value: SomeType): string in the next problem

Problem number 2

This place in the code would then again need a function that returns either the values as strings or empty strings so we don't get the error.

'applicant.firstname': "Riku"
'applicant.surname': ""
'applicant.dob': ""
'applicant.image': ""
