fix(Communities): don't list members in contacts to invite list

When inviting contacts to a community, Status Desktop suggests a list of
all contacts, even if contacts of that list are already members of the community.

This commit introduces a new flag to `ExistingContacts` component that
allows for configuring whether community members should be hidden or not

Fixes #2502
