[LyX/master] After export-cancel, hide busy and cancel buttons

[Scott Kostyshak]

commit 01abab9ad943bb2c89ef2a4c6a9acd8f695e5e54

    After export-cancel, hide busy and cancel buttons
    
    This is consistent with 70a71a82 (which is about the code path
    through clicking on the 'x' status bar icon).
    
    In the next commit I'll make a function to centralize this sequence
    of killing a script and emitting the scriptKilled() signal.
