invoice.expiration_in() equals the expiry block rather than the amount of blocks until expiry

It does this until the invoice is queried again and it corrects itself.
For example, I set expiry to 250 blocks, and .expiration_in() was 2867261 while creation_height was 2867011.

After using .expiration_in() function a second time, its value was set to 250.

Thanks for making this issue!

I was able to reproduce this by making the first expiration_in() call before any new blocks have arrived. Definitely counterintuitive behavior. Looks like it should be an easy fix though

The fix is on master, so you can point your project at latest master for now and I'll get this out in the next patch release.
