Fix Minor Issues

[teodorus-nathaniel]

Issues:

1. User that logs in not via polkadot is having onboarding modal appear every time because of stale data
2. User currently can't redirect to their own profile (if using Link, e.g. in if user clicks on their avatar in "Write something
   section")
3. Change share editor to use html editor instead of md, because emoji in md editor in iphone doesn't work
