plan.shared? should not use inactive roles

[nicolasfranck]

Please complete the following fields as applicable:

What version of the DMPRoadmap code are you running? (e.g. v2.2.0)

3.0.6

Expected behaviour:

plan.shared? should not use inactive roles

Actual behaviour:

If someone removes himself/herself from a plan by
hitting "remove plan", that roles becomes inactive,
but on the list of the people that still have access,
that plan is still shown as "shared", although there
is only one left but that person..

Reason: no filter on active role here

As this is addressed in the latest release, can we close the issue here?
