Move load annotations to service

- Load annotations using the new annotations service.
- Use the new store isFetchingAnnotations rather than the previous
isLoading method to determine whether an annotation fetch is currently
in progress.

Instead of going through a layer of indirection (aka the groups
service) to get the focusedGroupId use the store directly.

This service issues an api request(s) to fetch all annotations
associated with all URIs and the group on the page. It also
loads all the annotations into the store, updates the frame
status upon completion, and updates the activeAnnotationFetches
count in the store.

Bump eslint from 5.16.0 to 6.0.1

Bump @babel/preset-env from 7.4.5 to 7.5.0

 - Suppress all warnings about use of `hasOwnProperty`. Some of these
   warnings *are* valid issues. I've decided not to block the ESLint
   upgrade on them however.
 - Suppress two other specific warnings

Merge with `yarn.lock` updates on master.

This is the result of running:

    yarn upgrade -P @babel/core @babel/preset-env
