Re-ordering the icons of network shares (or any mounts) in the places panel does not save correctly. The first icon moved will have it's new position saved, subsequent moves will not. To re-order a bunch of icons, you have to move one, close dolphin, reopen dolphin, move the next one, close dolphin, etc etc until you have all of them in the order you want.

Reproducible: Always

Steps to Reproduce:
1. Re-order multiple network share icons in the "places" panel
2. Close and re-open dolphin
3. Only the first icon moved in step 1 will remain where it was moved to, the others return to their previous positions

Actual Results:  
Only first icon moved retains its new position

Expected Results:  
All icons moved should stay where they were moved to

Still present in Dolphin 16.04.1 (that version isn't on the list above)
KDE Frameworks 5.22.0
QT 5.5.1
xcb windowing system

This same bug has been present in Dolphin in debian unstable since _at least_ Jan. 2016 (unsure what version it was back then)
