Let's improve redirection from form to the forum

[tomislavmamic]

Issues:

1. User doesn't know how long until she is redirected or if she is going to be redirected at all.
2. User has to wait for automatic redirect, can't just go to the forum.
3. Text is too stretched to be easily read while the countdown is going.

Potential solutions

• Show countdown
  Maybe show a simple countdown so that user knows how long until redirect. Maybe say: "Redirecting in XXs."
• Add a link to go to forum immediate
  Maybe say: "Open now"

We have changed our mind about this. We will not redirect user to Forum, but to My projects page in app. There we will show the newly created draft proposal.

Also, after submitting, let's show a confirmation to the user like this toast message:
