Enforce hierarchical chart changes ordering

[josvazg]

groupChangesByChart was returning a map but we expected the result sto be ordered, in particular hierarchical ordered preferably.

This change turns groupChangesByChart into orderedChangesByChart by taking the mp generated before and passing it to orderByChartHierarchy which builds an array of ChartChanges and enforces the expected hierarchical order leveraging the chart full path: least deep paths go first, at the same depth level order alphabetically.
