Don't incorrectly find cycle in a generic impl (#4990)

If the `impl as` clause is on a generic interface, the parameters to the
generic may be constrained by _other_ interfaces. This then requires
another impl lookup, but it should be looking for a different impl since
it's for a different interface.

To avoid considering the same impl again, we discard it from
consideration if the interface itself does not match the interface being
queried.

Note that the query FacetType can have more than one interface in it
eventually, and a `context.TODO()` call is left to notify when we run
into this.
