UoM handling in iOS App differs from BasicUI

[pelerner]

Referring to #555

The behavior of openhab iOS App differs from the openhab BasicUI regarding UoM items, esp. max/min/step-values.

1. My UoM-item is defined in seconds — because the knx-device delivers seconds only.
   Number:Time iZEIT "item in seconds [%.1f s]" {channel="knx:…"}

2. The item on the Sitemap as a Setpoint in seconds works just fine in BasicUI and in openhab iOS App
   Setpoint item=iZEIT label="item in seconds [%.1f s]" minValue=300 maxValue=3600 step=60

3. The item on the Sitemap as a Setpoint in minutes works just fine in BasicUI and fails to recognize minutes in the iOS App
   Setpoint item=iZEIT label="item in minutes [%.1f min]" minValue=5 maxValue=60 step=5

The BasicUI handles the step value of “5” as minutes, OK.
The iOS App handles the step value of “5” as seconds, NOT EXPECTED BEHAVIOUR.

2. and 3) are expected to be functional equivalent.
   This is only true in BasicUI.
