Snippet replace when before prefix

[jrieken]

Tested all three cases for foo, f|oo and foo| work as expected but |foo doesn't.

Snippet

{
	 "Print to console": {
		"prefix": "foo",
		"body": [
			"console.log('$1');"
		],
		"description": "Log foo to console"
	}

}

• Put cursor before foo
• Trigger suggest
• Move focus to foo snippet in suggest widget
• Shift+Tab and Tab behave the same
