When the file loads, it's collapsed automatically
if the user has reviewed it already.

Unfortunately, this only happens when the component
mounts.

To make the component reactive - specifically in
file-by-file mode - we add the check for the collapse
state into a watcher on the file ID.

Critically, we leave the `mounted` check in place, too.
The first time the component is mounted, it has the
initial file already present - the watcher won't trigger
on that first render.

It's not very robust to retrieve a value by its position in an array.

Instead, because the files all have unique IDs we return an
object where each key is a file ID and it's value is whether that
file has been marked as reviewed.

This fixes the issue where the list of files in single-file mode
always has a length of 1, which means the fetched review is
always the first file in the MR.

Previously, the localStorage storage was the authoritative source.
Now, the Vuex store is the authoritative source, with the localStorage
store being the "backup"/persistent store.

That means we need to push the localStorage values into the app,
but reserve the `mrReviews` property for the mapped state.
We do this by renaming the initial hydrator to "rehydratedMrReviews".
