Fix crashes with FunctionHintProposalWidget

Browse Source 
The FunctionHintProposalWidget actually is not visible, but the
FakeToolTip popup is. That is also checked for visibility to decide
if we currently have a proposal open. Now, clicking anywhere
while the popup is open, closes the popup (as it is a tool tip).
The FunctionHintProposalWidget is never closed though, which is bad since
e.g. CodeAssistant expects the FunctionhintProposalWidget to die.

The patch just aborts the FunctionHintProposalWidget when the popup dies.
