Solving a block involves continously rehashing it, i.e. any extra calls to rehash it before are not necessary and can be dropped.

…o solving a9872e1 test: remove unnecessary block rehashing prior to solving (Sebastian Falbesoner) Pull request description: Solving a block involves continously rehashing it, https://github.com/bitcoin/bitcoin/blob/c9dd5c8d6e59e27af98e99d2844d6ead8eec3162/test/functional/test_framework/messages.py#L759-L764 i.e. any extra `rehash` calls before are not necessary and can be dropped. The instances were identified by searching for all block solving calls via `git grep "solve("` in `./test/functional/`. From 95 instances of `CBlock.solve()` calls, 20 contained an unnecessary rehashing instruction before that are removed in this PR.
