Issue Description

Trying to upload a file (as a logged in user), the request endlessly stales and the server errors with:

parse_1      | (node:1) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'enableForAnonymousUser' of undefined
parse_1      |     at createHandler (/parse-server/lib/Routers/FilesRouter.js:113:41)

parse_1      | (node:1) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 4)

Steps to reproduce

Get the docker-image (no custom configuration) try to upload a file as a regular user. The promise never finishes.

Actual Outcome

The server error's and the network never responds.

Expected Outcome

The server should accept the upload, store the file and respond

Thanks for reporting.

I was able to reproduce the issue, a PR is on the way.

The issue is that default values for fileUpload options are not applied.
Current workaround is to explicitly set the fileUpload options.
