Jehan bfc492fb1b Issue #4777: "New version available" after update. 
The About dialog refreshes the release information relatively to
currently running version before being displayed. No check of the remote
JSON file is done, it only verifies whether any stored released
version/revision is not same (or even lower) than the actually running
version. Indeed existence of a stored release means that a newer version
exists at check time only. On later run, this stored information may
have become deprecated.
