Test bug: durations test fail on non-US fractional number formatting (ie comma vs period)

[avocade]

Tests shouldn't fail just by changing the locale/region of the machine they're running on.

This is output from the test suite on my macOS machine. Swedish locale is set, which formats numbers as 40,3 instead of 40.3 by default.

I'll see if I can make a PR to fix this soon.
