Returned error treated when requesting uncommon URL

[joaoGabriel55]

Fix the irrelevant error returned when requesting uncommon URL - Open Issue #3509

When axios request to an illegal URL like "tel:484-695-3408", the error message is irrelevant.

TypeError: Cannot read property 'replace' of null
    at dispatchHttpRequest (node_modules/axios/lib/adapters/http.js:109:74)
    at new Promise (<anonymous>)
    at httpAdapter (node_modules/axios/lib/adapters/http.js:46:10)
    at dispatchRequest (node_modules/axios/lib/core/dispatchRequest.js:52:10)

So, I fixed this, validating the "path" property from "parsed" object, cheking if it is null, throwing an error message: "Malformed URL". And I checked too, if the URL protocol is supported (HTTP or HTTPS) throwing a message: "Unsupported protocol ".

I suggest that keep the URL validating behavior the same in both node an browser.

If I understand, this URL validating behavior (error messages) must be present too, in axios requests made by client (browser). Would be this?

[joaoGabriel55]

Currently, the URL validating are these:

Malformed URL:

Unsupported protocol:

Hello @buyan302, I simplely, used the same logic of my new error messages from node on xhr.js. And I added one more supported protocol: file:.

Waiting for your feedback.

Thanks.
