Cosmos-sdk: Better error handling for faulty seeds

[faboweb]

Version 0.17.0

If a user tries to import an account by using an old seed (12 words) the SDK panics. The expected behavior is, that there is an error message about a not acceptable seed structure.

Here is a log of this error:

That's definitely confusing. Perhaps we should track all the UX issues in the meta-issue? https://github.com/cosmos/cosmos-sdk/issues/1021

the UX issues has its own project: https://github.com/cosmos/cosmos-sdk/projects/18
I think #1021 is specific to error handling
