Review Comment:
We want to get a CatalogTable object from `UnresolvedRelation` here.
For all the sub-classes of `Table` trait, only `V1Table` and
`V2TableWithV1Fallback` can convert to a `CatalogTable` object.
And `HoodieInternalV2Table` self is a sub-class of `V2TableWithV1Fallback`
and have a method `v1TableWrapper` to get a `V1Table` object. So here i catch
the two pattern.
According to your comment, what if I change to "can not get a CatalogTable
from $table" or just remove this warning?
