Mitigate #1001871

The stack trace in the ticket is pretty old and doesn't match current line numbers. Do you have a newer one? In [#1001871](https://www.assembla.com/spaces/scala-ide/tickets/1001871) towards the bottom of the stack there's a call to `resetCompilers`, so I'm wondering if the call to `resetAllPresentationCompilers` won't lead to an infinite loop.
