runtime does not output inferred schema updates when a binding's target collection changes within the same task term

[psFried]

• Create a capture\
• ingest a document and see that the shard logs output an inferred schema updated message
• Update the capture binding to change the target from collection A to collection B
• ingest another document that's identical to the first

Expected: ingesting the second document should result in an inferred schema updated log.
Actual: no such log is produced

It seems that this map should include the collection name as part of the key, which would cause us to re-set the Shape when the target changes.
