Fix "+X other results" count in timeline hover

[sgalla]

Fix the +X other results counter in the timeline visual to be accurate in the case of multi valued date attributes. This number represents the number of additional metacard results and does not indicate the number of total date values.

timelineCounterFix.mp4

Testing:

1. Upload more than 5 files
2. Populate at least one value for datetime.start on each metacard
3. Open the timeline visual, select datetime.start, and verify the tooltip shows the correct number of "other results". For example, if you have 8 total metacards with non-empty datetime.start, you should see +3 other results
