a841194d28 Filestorage: Reuse IDBObjectStore throughout transaction 
- More like passing the same reference to it when calling db_get/set.
- In reality, it was still the same store object being accessed, but
this commit improves the coherence of the db_get/set helper methods.

83b283ebbe Filestorage: Replace the two server classes with a wrapper class 
Simplifies both the filestorage.js code as well as the starter.js code
that uses these FileStorage classes.

Now, the ServerFileStorageWrapper decorates the other FileStorage
classes by loading from the server when the file is not available.

Moreover, the previous starter.js was incorrectly passing the `baseurl`
parameter (it was passing it when baseurl was not defined nor needed).

a85dd50169 Filestorage: Improve assert coverage and robustness

Avoids ReferenceError when window is not defined e.g. on NodeJS.

c2dcb440dd Filestorage: Refactor fallback and load-from-server 
Fallback logic is moved to the caller's responsibility.

Empty FileStorages and FileStorages that load from the server are
separated into different classes. This is to avoid faults where the
caller of the constructor forgets to pass in a `baseurl` parameter and
leads to some confusing bug.
