Fix intermittent wallet.work_watcher_update failure (#2677)

Browse source 
This was due to sometimes the blocks having difficulty larger than `limited_active_difficulty` (min between trended_active_difficulty and `config.max_work_generate_difficulty`). Forcing the config value to a high value and the trend to immediately above the highest difficulty between the blocks is sufficient.
