[FIX] survey: fix incorrect behavior while retaking the test survey

Before this commit, while retaking a survey with 'Retry' button, the test
mode was not retained leading to unexpected behavior. This commit fixes the
issue by populating required parameters while retrying the survey that ensures
proper behavior for both test and non-test entries.
