Allow ignore refs set to be null

Plugins which uses global-refdb doesn't have to provide set of refs to
ignore.
Guice @Nullable and @Named annotation cannot be combined
together. If plugin will not provide list of refs to be ignored
exception will be thrown.

Make also all ignoredRefs ImmutableSet.
