The package name doesn't match the one used in
development_memtag_page.xml. This would result in the controller can't
be found when the DashboardFragment trying to instantiate the controller
defined in xml.

Bug: 245624194
Flag: EXEMPT low risk bugfix
Test: Examing the log and verify there is no "Cannot instantiate controller
from reflection" for DevelopmentMemtagFooterPreferenceController
