fix: transition import & SubmitError handling

[tenphi]

Fix Transition import
Submit error should follow the rules:

• Don't be shown if validation is failed
• Should trigger uncaught exception if the error is not handled properly (Error object, for example)
• SubmitError component should show the error only if it's a valid react element or a string. For other cases, it should show "Internal error" so we don't expose unhandled errors to the user.

If Form submission is failed on the validation step, then the onFailed callback is not fired.

all these cases could be easily covered with unit tests. Reach me in DM if you need some help

@MrFlashAccount I wasn't able to create a test that checks an uncaught rejection.
