fix offchain dns nametype + [root] validation

[storywithoutend]

User reported a bug where "sync manager" button appeared on his off-chain dns name. The source of the bug was that he also began the process of on-chain import by setting his dns-owner record.

Additional fix in this PR fixes the profile page for [root] where the invalid name warning and isNonASCII warning were showing.

This PR:

• Updates useNameType hook to check for ownerData before assigning on-chain dns name type.
• Adds additional unit tests for useNameType
• Fixes validation for [root] where isNonASCII is now false
• Fixes registrationStatus for [root] where it is now "owned" instead of "invalid"
