RAFT_TEST_CASE macro creates 2 test cases, one with random 20% packet
loss named name_drops. The framework makes hard coded assumptions about
leader which doesn't hold well in case of packet losses.
This short term fix disables the packet drop variant of the specified test.
It should be safe to re-enable it once the whole framework is re-worked to
remove these hard coded assumptions.
This PR fixes a bug. Hence we need to backport it.
