Should this lock also be used in other methods where the shared resources are accessed (read/write)?

We have a to-do in the code with a work item for doing better concurrency, #1215. TBH I'm tempted to do it separately.

Summary of the pull request
There is a bug where Dashboard can lose the order of widgets if some widgets are deleted (so the PinnedWidget count goes down, but the saved position index of the last widget stays the same) and then widgets are added (with a saved position index now less than or equal to the saved position index of the last widget(s). This change prevents this scenario by listening for when a widget is deleted, and then updating the saved position index of any subsequent widgets whose positions have now moved up in the list.
We stop listening to this event during drag and drop, since drop removes (and re-adds) a widget and takes care of re-numbering any affected widgets already.
