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`.

Start by locating the replaceAllObjects() and saveObjects() method definitions in the Java client and compare how the parameter is currently handled. Verify that replaceAllObjects() accepts the boolean while calls that omit it retain the false behavior; add or update coverage for both invocation forms if matching tests are present.
