Show folder previews for items that have a Places Panel entry

Summary:
informationpanelcontent.cpp currently has an explicit check for whether or not a URL has a Places panel entry, and if it does, no folder preview is generated. It's not clear why this is done, but it was reported as a bug: https://bugs.kde.org/show_bug.cgi?id=392621. Removing the logic fixes the bug.

BUG: 392621
FIXED-IN: 18.08.0

Test Plan:
Before:
{F5782793}

After:
{F5782794}

Detailed test procedure:
- Open the Information Panel
- Turn on previews
- Put some pictures in ~/Pictures
- Hover over it and see that the Information Panel shows a preview of its contents
- Add ~/Pictures to the Places panel
- Hover over it again and see that previews are no longer displayed
- Apply the patch and restart Dolphin
- Hover over it once more and see that there are now previews, yay!
