Rename "new draft" related items

[saulipurhonen]

Proposed solution

Legacy names for "new draft" should be renamed to "submission" as discussed in #533.

This should be done to all UI components, routes and variables where this naming has more accurate meaning.

DoD (Definition of Done)

Legacy names for "new draft" have been renamed to "submission"

Testing

Update tests to match new naming.

So, just to be absolutely sure NewDraftWizard should be renamed as SubmissionWizard and also in routes like <Route path="/newdraft" ....>
