fix: skip PublisherStalledCheck if PublisherOfflineCheck fails

[cctdaniel]

we agree that PublisherStalledCheck should fulfil these 3 requirements:

• should be skipped when market hours is closed
• should be skipped when publisher is offline (PublisherOfflineCheck fails)
• should be skipped when PublisherOfflineCheck returns true but distance > self.__abandoned_slot_distance

there seems to be 2 ways we can do this:

• duplicating the offline check logic in PublisherStalledCheck including modifying the check to accept max_slot_distance and abandoned_slot_distance fields which don't really seem to belong there since this is for PublisherOfflineCheck
• make sure PublisherStalledCheck runs after PublisherOfflineCheck and keep track of the deps with flags

instead of modifying PublisherStalledCheck to also accept max_slot_distance and abandoned_slot_distance solely for the purpose of replicating the offline check, I have chosen the second option in this PR which is to modify check_publisher() so that we don't have to duplicate the offline check, this is definitely not without its drawback, which is that now the check_publisher() function becomes more complicated

update: previously I've tried to approach this issue using option 2 but it turns out changes the code to be more complicated and introduce dependencies that will make it more unmaintainable so I have reverted to the first option instead
