Try to fix BookmarkEditorControllerNoNodeTest.NoNodeNoTree

displayName is set to initialName in -[BookmarkEditorBaseController
awakeFromNib], and initialName is [@"" retain]. This seems to return a new
object with clang but the same object with gcc.

Not relying on internalized strings seems cleaner in general.
