resolves #1542

• There was an issue when loading new annotations from a pipeline or other that would cause it to not render properly. This would also then cause errors when modifying annotations by deleting or other actions.
  • This can be replicated by loading up dataset with multiple revisions and jumping between revisions in the web version and watching the console. After the errors some undefined behavior occurs like being unable to delete items as well as making it so jumping to other revisions doesn't always update data.
• The root cause was the LayerManager.vue attempting to graph trackIds that didn't exist anymore.
  • The loop for watching the frame and getting the tracks that intersect with the current frame would be done outside of other loops and could cause an instance when data is reloaded that it would attempt to grab tracks that don't exists.
  • Swapping the trackStore.get to a trackStore.getPossible allows it to properly return undefined instead of throwing an error when a trackId isn't found
• Noticed an issue with using the revision history and returning to the main data. I've updated it to use the same function with an undefined Revision Id that way it would properly reload the annotations.
