Sort components by name in HistorySvc dump

Recently I noticed that the test exercising HistorySvc was unstable.

I found out that the order of the dump at the end of the job is by component pointer, which is undefined, and changes if we make changes affecting the memory layout.

With this change I sort the dump by component name.
