Added a call to pLayout->ClearAutoInsertionsHighlighting() back to the CPhraseBox::JumpForward() handler. It appears that BEW had accidentally removed this call which functioned to remove auto-insert highlighting when Enter/Tab is pressed, and that dated back to 2012. The call appears to have been accidentally removed when removing other surrounding code that was added temporarily in attempts to fix the issue of not being able to move the Phrasebox forward after the merger of a phrase.
