glob throws a TypeError when called with an empty string

[kapooostin]

Environment

• OS Version: macOS 10.14.6
• Node.js Version: 10.15.3

Actual behavior

glob throws a TypeError when called with an empty string, but rejects with a TypeError when argument is undefined or null

Expected behavior

The behaviour should be consistent. Either all the TypeErrors should be thrown or put in a rejection branch.

Steps to reproduce

1. run fast-glob with an empty string
2. compare output to a run with undefined or null

Code sample

import fg from 'fast-glob'

console.log(fg('')) // TypeError: Expected a non-empty string

console.log(fg(null)) // Promise <rejected> TypeError: Patterns must be a string or an array of strings

Will be available with fast-glob@3.2.0 (#251).
