watch:test triggers infinitely because its watching generated files

[kevinramharak]

When running npm run watch:test I notice the following output:

> @vscode/vsce@0.0.0 watch:test
> npm run test -- --watch


> @vscode/vsce@0.0.0 test
> mocha --watch

⚠ [mocha] cleaning up, please wait...

This is caused because of the following glob in package.json

"mocha": {
	"require": [
		"ts-node/register"
	],
	"watch-files": "src/**",
	"spec": "src/test/**/*.ts"
}

The tests will generate files and folders in src/test/fixtures/ causing an infinite trigger.

Looks like it is caused by node-tmp being used to create temporary directories in 2 test cases. node-tmp always uses the tmp- prefix unless changed with an option, which no test does, so adding:

"watch-ignore": "src/test/fixtures/tmp-*",

To the mocha options will fix the loop.
