[Bug] Selected Segment is not used when iterating over

[xbankov]

Describe the Bug

The iterating over the segments and selecting a segment are not aligned. I can select the segment from the menu, and then iterate, but it iterates from the segment it iterated over before, not the one selected.

Steps to Reproduce

1. Go to https://viewer.ohif.org/viewer?StudyInstanceUIDs=1.3.6.1.4.1.5962.99.1.2968617883.1314880426.1493322302363.3.0
2. Open RTSTRUCT
3. Do not load the segmentation.
4. Open right panel menu with segments/labels shown.
5. Click on any - Segmentation highlight
6. Iterate over the next segment using arrow.

The current behavior

It starts iterating from 0 even though you have just selected different segment.

The expected behavior

Iterates over the next segment in the menu.
