feedback: Do not create a new instant if one exists already

When an instant of the new feedback app has been created, further
request to open the app again should reuse the existing instant.

Current behavior:

- The existing instant is unloaded.
- A new instant is created.

This may cause the description entered get lost.

- Check whether there is an instant existing already.
- If yes, simply show it.
- If no, launch a new instant.

Bug: b:283145415
Test:
  1) press ALt+Shift+I to open the feedback app.
  2) Enter some text, say "testing...".
  3) Click the "Tips on writing feedback" link.
  4) Observe that the link is opened and its page is focused.
  5) Visit About Chrome from settings, click "Send Feedback".
  6) Observe that the feedback app is brought back to focused.
  7) Observe that the text entered before is still there.
