/**
 * Remove old information from a PersistentSessionsStore so that it respects the
 * given `limit` as a maximum size. This can be used to prevent its size from
 * growing indefinitely.
 *
 * This is needed because our persistent session information storage is
 * un-bounded in size, adding more data will just add more data without removing
 * the old one - which can be valid or invalid.
 *
 * This is problematic for at least two reasons:
 *   - This data is loaded into JS memory which is finite (and which maximum
 *     bounds depends on the user environment).
 *   - The final storage used (as chosen by the application using the RxPlayer)
 *     will in most cases have a maximum storage size.
