BUG: UNC paths aren't resolved correctly

Can't use a remote network path on windows, globs aren't resolved correctly.

Given an existing remote resource
```
C:\Users\user>dir /B \\192.168.1.2\fle.txt
file.txt
```
`src()` fails to access it correctly.

### What were you expecting to happen?
Remote `file.txt` correctly copied to `./local'.

### What actually happened?
No file was copied

### Please give us a sample of your gulpfile
```js
// CASE A: using forward slashes
const remoteFile = '//192.168.1.2/file.txt';
src(remoteFile).dest('./local');
```
```js
// CASE B using (escaped) backward slashes
const remoteFile = '\\\\192.168.1.2\\file.txt';
src(remoteFile).dest('./local');
```

### Terminal output / screenshots
```sh
# CASE A
Error: File not found with singular glob: //192.168.1.2/file.txt (if this was purposeful, use `allowEmpty` option)
at Glob. (D:\testing\node_modules\glob-stream\readable.js:84:17)
...
```
```sh
# CASE B
Error: File not found with singular glob: D:/testing/\\192.168.1.2\file.txt (if this was purposeful, use `allowEmpty` option)
at Glob. (D:\testing\node_modules\glob-stream\readable.js:84:17)
