Bug#1028595: debmake creates invalid debian/source/control

[Pirate Praveen]

Package: debmake
Version: 4.4.0-1
severity: important
and debian/tests/control is empty creating two lintian errors

E: birdie-alarm-mobile source: unknown-file-in-debian-source 
[debian/source/control]
E: birdie-alarm-mobile source: empty-debian-tests-control 
[debian/tests/control]

so debian/source/control should be moved as debian/tests/control
