Fix on-call schedule timeline width calculation
What does this MR do?
Fixes an issue with the oncall width timeline.
The display of shifts is based on the width of the timeline. This data is being measured incorrectly, and this undermines the position and size of the displayed shifts.
Where we should be measuring the width of the displayed area, instead we are measuring the width of the whole timeline, including the rotation names to the left of the displayed area. This MR fixes that, ensuring the width calculation is correct.
This was introduced in the timeline refactor: !58204 (merged) / !58322 (merged) / #324608 (closed)
issue here: #327300 (closed)
