test: fix timeout hiding runtime build error

[patak-dev]

Description

Setup for the screenshots: I forced a runtime build error, by using configResolved to get the config in an internal plugin. This is ok according to the public API of vite, but internal plugins don't get this hook called (and you should directly get the config through params).

In the current test output for ssr-react, the build failed but the tests continued to run and trying to use await page.click caused a timeout that is reported and hides the real issue

This PR closes the page if there is an exception during the test setup, resolving the await and timeout issue. The real error gets properly reported but it is duplicated, as logLevel: 'error' is used to do the builds for the test suite so it is reported both by Vite and by Jest.

To avoid this, the logLevel is set as 'silent' so the only reported exception is logged by Jest

Note: I included both changes in the same PR because in the current test setup we don't have the duplicated log error.

Additional context

The Jest log is a lot better than the one generated internally by Vite, it would be good to see if we could get the same output when the user uses the cli.
