Christian Soffke 9a84e9eb34 tree: fix return to root after adding to existing playlist 
When adding files to an existing playlist from
the database or file browser, Rockbox returns to
the root menu afterwards.

Appears to be a regression introduced in commit 72c539d
for the file browser. For the database, it has only
become noticeable since commit 188f025
