Agreements: Hide accordions in Agreement view where there is no content

Purpose:
Remove clutter from screen by hiding most accordions if they don't have content

Description:
In the Agreement view pane, the following accordions should be hidden if there is no content to display in them (i.e. their 'count' in accordion banner is zero)

• Internal contacts
• Controlling license
• Future licenses
• Historical licenses
• External licenses
• Organizations
• Supplementary documents
• Usage data
• Related agreements

In addition the "License and business terms" accordion should only display where there is controlling license set (this is the same basis used currently for the display of the emptyAccordion.licenseAndBusinessTerms message in the UI)

The rules for the display of the Periods accordion are different and handled in ERM-1531
The Notes and Agreement Lines accordions should display even if the counters are zero because the user can add new Notes/Lines from the Accordion in the view pane.

User story statement(s):

As a ERM user,
I want to only see relevant information on the Agreement view
so that I'm not distracted by unpopulated sections of the agreement
