Introspecting indexes on embedded documents leads to validation error

[janpio]

Currently indexes on fields of embedded documents lead to creation of a not really existing field in the parent model, and an index on that. The index uses a dot in its name, which is not allowed right now.

This should go away when we actually support indexes on embedded document fields via #10101
