Subject: [PATCH] Open new instance of Dolphin if no URLs are given

Summary:
BUG: 408387
BUG: 408244
FIXED-IN: 19.08.0

Currently Dolphin only opens a new instance of itself in the following two scenarios:
1. No other Dolphin instances ( D21666 deals with not matching daemonized instances) are currently running.
2. A new instance is explicitly asked for via:  `dolphin --new-window`

A third scenario is needed to fix this bug:
3. If no URLs are passed in as arguments then open a new instance.

This patch adds this third scenario.

Test Plan:
STEPS TO REPRODUCE
1. Open Dolphin
2. Right-click on Dolphin's Task Manager Entry and click "Start New Instance"
3. A new instance is created.

As my system stuff is not built on master I am unable to replicate the bug (and can't confirm whether this fixes it), hence I'll rely on @ngraham to confirm whether this patch fixes the issue.
