Open of new terminal doesn't show processes tab

[mmorhun]

When try to open a new terminal focus doesn't switches to it, if Processes tab is hidden.

Reproduction Steps:

1. Open a workspace
2. Make Processes tab inactive (hide it or open another one: Usage or Events, etc.)
3. Try to open terminal using Menu -> Run -> Terminal or using shortcut Alt+F12

Expected behavior:
New terminal will be showed to user

Observed behavior:
Terminal is opened, but not shown (to see it, is needed to manually switch to Precesses tab). It is uncomfortable and might confuse users.
