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
be82c40703 (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.
