Unit Tests: Remove block reward upper bound size checks

Tests running after being compiled with `make debug-test` failed with
```
[  FAILED  ] block_reward_and_current_block_weight.fails_on_huge_median_size
[  FAILED  ] block_reward_and_current_block_weight.fails_on_huge_block_weight
```

With the introduction of the patch in
https://github.com/monero-project/monero/commit/be82c40703d267184ee07bf7be71002122c86656#diff-1a57d4e6013984c420da98d1adde0eafL113
the assertions checking the weight of the median and current block
against a size limit were removed. Since the limit is now enforced by a
long divisor and a uint64_t type, checking in a separate test makes
little sense, so they are removed here.
