test: Reset mocktime in the common setup

Doing it there will reduce code bloat and also ensure no test can "forget" to reset it

ACK fa40d6a1c47ac7f3dc6c11a2e6642cfef95422c1

This gives us tighter control of time and will prevent any time slippage making this test fail. I couldn't make the banned time test fail in practice, but this prevents that.

As predicted, this happens in practice:
```
test/rpc_tests.cpp(292): error: in "rpc_tests/rpc_ban": check time_remaining == banned_until - now has failed [200 != 199]
```
