Show loading indicator for workspaces

[cimfalab]

If I land to the dashboard after log-in,
I see empty Workspaces page for some seconds.
Because loading workspaces takes some time (can it be reduced?)
I often misunderstand I have no workspace or there is an error.

So I think it's better

• add loading indiator
• or display page after loading workspaces completely

Please check.

That's good idea. Thank you!
