Bartosz Dziewoński f7d98d7690 Redo wrapper for localStorage integration
I think the issues in T329299 are caused by partially autosaved
comments. We store data in multiple localStorage keys, and if some of
them are stored but others are not (due to exceeding storage quota),
our code can't handle the inconsistent state.

We already have a wrapper around localStorage that tries to cover up
these issues. Change it so that all values specific to an instance of
a reply tool are stored under one localStorage key. This ensures that
all updates consistently succeed or fail, with no partially stored
state.

One of the reasons we haven't done this is because this requires the
whole data to be serialized to JSON every time, but our experience
with VE change 4355d697aa shows that this is fast enough.

Extra changes:
* Remove storagePrefix, now redundant
* Remove use of createConflictableStorage, now redundant
* Prefix the key with 'mw' as advised by mw.storage documentation
* Use ES6 syntax for the new code (just for fun)
* Use consistent expiry (T339042)

Bug: T329299
