CPVM: move focus on input area after clearing clipboard

[weizhouapache]

Description

When click "Clear" button in the clipboard dialog on vm console, the input area is cleared but the page still focuses on the "Clear" button.
It is inconvenient for end users as normally users want to re-input after clearing the input.

This PR moves the focus on the input area after clearing.

[LL] Trillian Build Failed (tid-7026)

[DaanHoogland]

tested in a lab env; can enter any command and send it. If followed by a newline it will be executed. pressing clear will focus on the edit box and a new command can be entered.

(too bad paste from the console back doesn't work)
