Instead of removing the demo data (demo data is our friend), make the test more
specific, adding a date to match the rate of 1.5289 all year long.
Old demo data hardcoded the currency rate of USD to 1.5289 at the half
of the year, introducting new year red runbot.
Using assertAlmostEquals to avoid values like 32.730000000000004
