Search completion unactivated by default

[PierreMardon]

Description

With my installation / setup scenario, I was unable to have predictive search working easily.

Steps to Reproduce

1. Install Brave
2. Choose to migrate settings from Chrome (that had a full Google configuration)
3. Not sure: switch search engine in the settings
4. With Qwant as search engine, try to get some predictive search from the URL bar
5. As it failed, go to settings and enable the predictive search service
6. Search again "popular" words like trump => still failing
7. Go to settings to switch search engine to some other value and back to Qwant again
8. Yay, now it works!

Actual result:

No predictive search results even after activating the setting.

Expected result:

Predictive search result enabled and working:

• just after install + migrate from Chrome where it's enabled by default (?)
• at least after enabling it in the settings

Reproduces how often:

Only once, didn't try again

Miscellaneous Information:

Sorry for not trying with specific builds or trying to toggle brave specific features. My experience the last few days with brave was so nice that I wanted to report the only small bug to kind of help, and that's it.

Only extra things I installed:

• Dark Reader extension v4.8.5, enabled by default on every website
• Google Windevine :'(

Marking wontfix. For privacy reasons, we don't enable autocomplete search suggestions by default.

I'm not sure you got my point @rebron :

5. As it failed, go to settings and enable the predictive search service
6. Search again "popular" words like trump => still failing

This is definitely a bug. I had to switch the selected search engine to make it work properly.
