The user-specified seed phrase during the first-time-flow import step
required the phrase to be entered in all lowercase. The case does not
add any extra entropy to the seed, so there's no reason to be case
sensitive. Flexibility here will improve the onboarding UX.
This commit makes the entered seed phrase case-insensitive.

Fixes#6694
This changeset fixes our parsing of seed phrases during import to handle the
case where a user tries to import a seed phrase that consists solely of whitespace.
We no longer produce an error and instead treat it as an incorrect seed phrase.
* Handle importing more invalid seed phrases
