Previously, any attempt to take a materialized view or secondary index
snapshot was considered a mistake and caused the snapshot operation to
abort, with a suggestion to snapshot the base table instead.
But an automatic pre-scrub snapshot of a view cannot be attributed to
user error, so the operation should not be aborted in that case.
(It is an open question whether the more correct thing to do during
pre-scrub snapshot would be to silently ignore views. Or perhaps they
should be ignored in all cases except when the user explicitly asks to
snapshot them, by name)
Closes#10760.
