Loading repo show activity progress bar

[eddiejaoude]

When adding a repo to the project, it takes a while to appear if a new repo to DashboardHub.

I think we can activate the progress loader with a flag:

• repo is added and data is loading add isLoading = true flag
• when data is loaded isLoading = false remove flag once function to get all repo data is complete

Check loading (flag) appears when doing also:

• repo force refresh

Put isLoading = true flag in repo info function before and when complete isLoading = false
