prop250: Fix unit tests about the RSA fingerprint check

Browse Source 
Code has been changed so every RSA fingerprint for a commit in our state is
validated before being used. This fixes the unit tests by mocking one of the
key function and updating the hardcoded state string.

Also, fix a time parsing overflow on platforms with 32bit time_t
