Fix resetRetrieveHandlers to reset retrieveSourceMap and retrieveFile functions

ArtemGovorov · web-flow · commit 16f1a6d847ce · 2019-02-22T13:39:24.000+10:00
The `handlerExec` function produces functions that are using original `retrieveFileHandlers`/`retrieveMapHandlers` references, so because the array variables are re-assigned in the `resetRetrieveHandlers` function, `retrieveSourceMap` and `retrieveFile` need to be re-created to point them to correct instances of `retrieveFileHandlers`/`retrieveMapHandlers`. This fixes: jestjs/jest#6424 jestjs/jest#7402
