Only mark group as failed to load for summary 

Currently, any error in the `GroupStore`s several requests can cause the whole
`GroupView` component to hide and be mark the group as failed to load.

Since it is known that group members may fail to load in some cases, let's only
show failed to load for the whole group when the summary fails.

This also strengthens the `GroupView` test by ensuring we wait for multiple
updates for checking results.
