Workaround for Croatian TimeSpan localization bug

[hangy]

This fixes #597 by using the same value for both resource keys. As far as I found out "dana" is the general plural for days, and the postfix is not required. However, the method that gets the resource key does not know that it is not formatting numbers but timespans at this point, so I think this workaround is the best available quick fix for the bug.

Apologies in advance, if the first CI tests fail and I need to re-adjust something. I'm having a bit of a problem getting VS to run the 22k unit tests, and the build.cmd doens't seem to work well right now, either.

I'll see what I can do about fixing build.cmd, but in the mean time, three tests are failing:

Is this ready? btw, the latest dev branch should have build.cmd fixed.

Yup, this should be good to go. I'll try the fixed build.cmd during the weekend, thanks! 👍
