Funny little 'bug' on network stats page.

Hi @Maniu -- I just noticed a little issue which I thought I should report:

This is on a network where the main site does not have a dedicated GA code, only one GA code set on the Network level with Google account connected. Now, if I go to the Network Dashboard > Statistics page, then go to "Last 3 Months" and then to "Last Year" (or back to "Last Month") I suddenly find myself on the main site admin level instead of on the Network admin level.
