Allowing IntentPicker to be launched in single user mode.

For Intent redirection from Private Profile to main user,
we do not want to show the work tab in intent picker,
when there are more than 1 app in main user.

In this change we pass a param to ResolverActivity, which
allows the picker sheet to be constructed in single user mode.
