"Create new group" button is not visible until after account is member of at least one group

[TheTomcat14]

Bug Description

I wanted to test the "User group" functionality in Friendica.
I did so based on this Documentation entry: https://wiki.friendi.ca/docs/groups-and-privacy

Upon browsing to the "Network" page, the "Create new group" button was not visible.
Clicking on the "Groups" link under the "Circles" box did not give any of the possibilities described in the documentation.
(I guess that's because User groups aren't circles but instead "Community accounts")

The "Create new group" button on the Network page only displays when the account is already a member of at least one group.

I think this is because of the code in src\Content\GroupManager.php, line 125
if (DBA::isResult($contacts)) {

The DBA::isResult() function checks if the result contains at least one result.
If there are no results then the whole widget, including the add group button, is not rendered.

Steps to Reproduce

1. Create an account and login
2. Go to the Network page
3. No add group button is visible
4. Go to the "Settings" of your account
5. Click "manage accounts"
6. Register an additional account
7. Switch to that additional account, go to the settings and change the advanced account type to "community group"
8. Switch back to the parent account
9. Follow the community account you just created (if the follow request needs approval, switch back to the community account and approve it, after approval switch back to the parent account)
10. In the parent account go to Network, the group widget will now appear together with the "create new group" button
