DPL-nnn Edit batch save should redirect to batch page

[JamesGlover]

User story As a sequencing manager I would like the batch edit page to redirect back to the batch page on finishing editing.

The behaviour was recently updated as part of https://github.com/sanger/sequencescape/issues/3323 to improve data-integrity, however I forgot the sequencing teams use the page, as well as the QC teams. So this use case was missed.
