Fix client-switching bug

Summary:
When a new client connects, we dispatch the NEW_CLIENT event.

The reducer of this event contains logic for determining if flipper should switch to display the newly connected client or not, and if so, it will dispatch SELECT_CLIENT.

For that reason, flipperServer always dispatching SELECT_CLIENT bypasses the "should switch?" logic and always switches whenever a new client connects. This is disruptive to working and not desired.

Removing this dispatch so that we rely on the NEW_CLIENT reducer to decide.
