tengqm 3d2b7facda Make all assertEqual() calls conform to convention
It is a convention to have assertEqual() assertions invoked with
'expected value' before 'actual value', or else the debug output may
become very confusing.  This patch fixes about 100 violations in current
test cases where about 3580 assertEqual calls are made.

Closes-Bug: 1259292
