fix: restart on config file change crashes

[AriPerkkio]

Fixes #2393.

Changes the order of Vitest.start() (src/node/core.ts) call when server restarts.

Execution order before

• cli::start
  

  vitest/packages/vitest/src/node/cli.ts

  Line 118 in b51cda3

  async function start(mode: VitestRunMode, cliFilters: string[], options: CliOptions): Promise<Vitest | undefined> {

• plugins::setServer
  

  vitest/packages/vitest/src/node/plugins/index.ts

  Lines 172 to 174 in b51cda3

  	async configureServer(server) {
  	try {
  	await ctx.setServer(options, server)

• core::setServer
  

  vitest/packages/vitest/src/node/core.ts

  Line 58 in b51cda3

  async setServer(options: UserConfig, server: ViteDevServer) {

• core::start
  

  vitest/packages/vitest/src/node/core.ts

  Line 200 in b51cda3

  async start(filters?: string[]) {

• Make change to configuration file

• core::server.watcher-change
  

  vitest/packages/vitest/src/node/core.ts

  Lines 98 to 103 in b51cda3

  	server.watcher.on('change', async (file) => {
  	file = normalizePath(file)
  	const isConfig = file === server.config.configFile
  	if (isConfig) {
  	await Promise.all(this._onRestartListeners.map(fn => fn('config')))
  	await serverRestart()

Restarting due to config changes...
