TerminalProcess: Fix stopping the terminal

Browse Source 
Fixes 30 seconds freeze when stopping the terminal
during debugging (when being interrupted on some
breakpoint).

Fixes also the freeze on closing the preferences
dialog after opening the remote shell via
"Open Remote Shell" and keeping it open.

Fixes: QTCREATORBUG-28365
