feat(workers/repository): Update package files in the same order they're extracted

[mbudnek]

Changes

For some managers that can have dependencies between input files (pip-compile, for example) it's important to update each input file in the correct order. This changes getUpdatedPackageFiles to sort its lists of package files into the same order that they were returned by the manager's extract function.

Since package files can be referenced by multiple managers and since each manager could return the package files in a different order I also inverted the update logic from

for each package file
    for each manager
        manager.update(package file)

to

for each manager with updated package files
    sortPackageFiles
    for each package file
        manager.update(package file)

This lets us sort the list of package files only once per manager.

This type of large core logic change is risky and will take a long time to review/approve/merge

this needs to be carefully reviewed as it's also significant for performance
