Preprocessor does not fire "close" event

[bahmutov]

Seems to be a bug.

I expect to see "close" events fired when closing / stopping tests, but do not see any messages about this. This would cause problems running in GUI mode, especially when using custom preprocessors to bundle spec files.

packages/server/lib/plugins/preprocessor.coffee

Running against cypress-test-tiny with debug log messages enabled

So I see getFile and set default preprocessor messages, but not anything related to close event.

Also noticed same in cypress-io/cypress-example-recipes#136

Looks like it fires when switching files or closing a project, but not when closing the browser. Good catch! Working on a fix now.
