Navigating to a folder in trash and up moves user out of trash:///

[Andrzej Mendel-Nykorowycz]

Ubuntu version: Ubuntu 15.10
Nautilus version: 1:3.14.2-0ubuntu13

If a user opens a folder in trash:/// and then navigates up, he ends up in ~/.local/share/Trash/files rather than in trash:///. If he then tries to delete said folder, it simply gets moved to trash again, since Nautilus does not recognize ~/.local/share/Trash/files as a special location.

Steps to reproduce:
1) In Nautilus, create a folder names 'foo'
2) Delete 'foo' by moving to trash
3) Open trash
4) Open 'foo' in trash
5) Navigate up
6) Delete 'foo'

Expected behaviour:
'foo' is permanently deleted

Observed behaviour:
'foo' is moved from trash to trash, i.e. nothing happens
