Manager remote control doesn't activate session until tab is focused

[dgershman]

Bug

When using the Manager tab to remote-control a session (e.g. via crow send), the session doesn't actually proceed/activate until the user manually logs in and switches to the active tab in the Crow UI.

Expected Behavior

Sessions controlled via the Manager should activate and proceed without requiring the user to manually focus the tab or log in.

Steps to Reproduce

1. Use the Manager tab to send commands to a session via crow send
2. Observe that the session doesn't proceed
3. Manually switch to the session's tab in the Crow UI
4. Session now proceeds as expected

Impact

This defeats the purpose of remote control from the Manager — the user has to babysit each session by switching to its tab.
