ManufacturerController: don't distort manufacturer description.

While a manufacturer's description is expected to be HTML (and
gets edited using TinyMCE), it was recalculated like this, from:

  <p>line 1</p>
  <p>line 2</p>
  <p>line 3</p>

to:

  <p>line 1</p>
  <br>
  <p>line 2</p>
  <br>
  <p>line 3</p>
