Fix an expansion flag issue where it expands to a repeatable flag.
There's no reason an expansion flag should not expand to multiple values for a repeatable flag (a flag with allowMultiple set to true.) If this expansion flag is set in a SetValue policy, group its repeatable subflags into a single SetValue per subflag.
For an overridable SetValue policy on an expansion, any repeatable flag that it expands to should append its value, and not override the user's original values.
