Investigate more use cases for embedded collections and query resolution

[cesarParra]

Investigate if we would want to do the same thing with other functions that we do with the WHERE function in the ContextResolver, where the query itself is returned for continued resolution in the case of embedded collections that also returns records back. For example FIRSTWHERE, LASTWHERE (and there might be more use cases, for example, what if the function ends up returning the $current?)
