Prevent the member count inside a space from disappearing

[JammingBen]

Description

We've fixed a bug where opening the sidebar for a file inside a space caused the member count of the space to disappear.

Also reduced the complexity a bit by removing the loadSharesTask within a space. Counting the members can now be done via the space object itself thanks to #6545.
