0ca4c8b3c6 Changed functional tests which do not require wallets to run without (sanket1729) Pull request description: Addresses #14216 . Changed Changed `get_deterministic_priv_key()` to return named tuple`(address, key)` I have tried to be exhaustive as possible in maximum coverage for non-wallet mode without affecting any coverage for wallet mode. However, I could not check the tests in wallet mode because of timeout issues. Hopefully, travis job checks those. Tests `feature_block.py`, `feature_logging.py` and `feature_reindex.py` were skipping despite having no direct dependency on any wallet functions. So, I have also disabled the `skip_test_no_wallet()` for those files too.
