Title: Fix reported issues in debugger and error management

- debugSource of some specific kinds of paths under Windows shows an error message: correctly detect absolute paths on the Windows desktop platform
- setting `options(error = NULL)` permanently disables the RStudio error handler: don't record the error handler in user settings unless it was set during startup
