Adding another study should force a plate mapper update

This currently doesn't happen, but it would make sense to have this sort of functionality available (discussed this with @charles-cowart).

As an example: say the user enters in some specimen IDs associated with "Study 1", but no studies have been added for the given plate yet. These IDs would all show up with a red candy-stripe background.

If the user then adds Study 1, these specimen IDs will remain with a red candy-stripe background. This will only change when the user forces an update by changing individual IDs to something else, then changing those IDs back.
