Repro steps:

Run any query on a sharded view (view A backed by collection B).
After the 'CommandOnShardedViewNotSupportedOnMongod' is raised and while mongos is resolving the view, we drop collection B and recreate it as view B on collection C.
We will finish the query but not apply the view pipeline from view A and only apply view B's definition.

Found and related to the viewless timeseries upgrade/downgrade effort (see ~~SERVER-120567~~), but it is not specific to viewless timeseries.

is depended on by

SERVER-120567 Queries on views over a timeseries collection are racy with FCV upgrade/downgrade
