* Add check for preexisting wallet * Reminder * Create another check. Adjust tests * Wording in comment * Remove unnecessary logic. Add another regression test. * Spacing * Prepare to merge master * Refactor wallet checks * Fixed test * Revert back to original location of check * Fix test * Fix test * Address linter feedback * Align CreateWallet() with recent changes * Align RecoverWallet with recent changes * Correct test error message * Refactor test to minimize duplication * rename to isValid and adjust function code * refactor * Improve IsValid() * Fix tests * Remove comment * Fix documentation of IsValid() * Align behavior of OpenWalletOrElseCli * Fix tests * Realigning error msg with prior behavior * Fix another test * Correct logic * small change in logic * Fix err messages * Create consts for repeated strings * Add comments to new constants * gofmt * Adjust WalletConfig behavior so it is closer to prior-to-PR. Adjust test accordingly * adjust error messages Co-authored-by: dv8silencer <15720668+dv8silencer@users.noreply.github.com>
