always use static keys in tests (#2928) There are multiple ways how states can be processed during tests. One is through tests/mocking, the other through tests/xxxutil. Both methods can create genesis states with a set of deposits from mock validators. The private keys for those validators are created differently, though. While tests/mocking generates random keys, testblockutil generates fixed keys. This is a problem when mixing both tests/mocking and testblockutil in a single test case, as they assume that the deposits were generated using the same method. This patch aligns the key generation across tests.
