[Owncloud] fixed redirect to desired page after login

[Michiel de Jong]

Hi!

Since the new routing, if the user is made to log in, we were always
sending her to the 'files' app, not to the page where she actually
wanted to go. There was also htmlentities() in the redirect header
which made no sense IMO.

As this is quite important code, i was waiting for someone in
owncloud-dev to look at it together, but in the end i just committed
this:

http://gitorious.org/owncloud/owncloud/commit/ea33b4aaa104252ff344e93a434e6c2eedcf438b/diffs/9b5e8a2c634e07d9c6e1693158e224eda7e5f673

So maybe Georg or someone else should check if this is what was
intended. At least it was broken before, and this commit fixes it.
Have a nice release! tomorrow, right?


cheers,
Michiel
