Handle `autoGenerateObjectIDIfNotExist` parameter for `replaceAllObjects()` method

The `autoGenerateObjectIDIfNotExist` boolean parameter is for now only valid in
the context of the `saveObjects()` method. As pointed out by @julienpa, it would
make sense to also accepts it as a valid parameter of `replaceAllObjects()`.

For backward-compatiblity, let's make sure the default behavior of calling
`replaceAllObjects()` without the `autoGenerateObjectIDIfNotExist` parameter is
still considered as if it was set to `false`.

Find the Go implementation and tests for replaceAllObjects(), then compare its parameter handling with saveObjects(). Verify that the parameter is accepted for replacement requests, that omitting it preserves false behavior, and that tests cover both the omitted and enabled cases.
