Text file remains on screen after being deleted

Expected behaviour

When pressing the trash can to delete a viewed text file, the interface should return to the directory listing after deleting the file.

Actual behaviour

The deleted text file remains on the screen. It looks like a similar problem was attempted to be fixed for issue #598
Note: the file is correctly deleted. It simply remains on screen until you manually return to the directory listing, at which point you can verify that it was truly deleted.

Steps to reproduce

• View a text file
• Tap the trash can icon at the bottom of the screen to delete it and notice that the file remains viewed. It appears as though nothing as happened.
• Tap the back breadcrumb to return to the directory listing and notice that the file was, in fact deleted correctly.
