Environment

• OS Version: macOS 10.14
• Node.js Version: 8.11.4

Actual behavior

The output of fast-glob contains duplicates when using non-normalized paths in patterns (like ./file.txt).

Expected behavior

Duplicates should be avoided.

Steps to reproduce & code sample

Let's assume the working directory contains the following files: file1.txt and file2.txt

fastGlob.sync(['*', './file1.txt'])
// returns ['./file1.txt', 'file2.txt', 'file1.txt']
// where I'm expecting ['file1.txt', 'file2.txt']

I just wanted to raise the issue, though I'm not sure if this is an actual bug or if it's wanted.

Cheers
