All subsequent tests will be skipped if throw non Error

[farwayer]

Thanks for the nice lib! Just started using it and found a bug:

test('example', () => new Promise((resolve, reject) => {
  reject()
})

test('example', () => new Promise((resolve, reject) => {
  reject("reason")
})

test('example', () => {
  throw "reason"
})

As result test fail will be silently ignored. The bug is here: format function expects that err is defined and is Error instance although this is not required.

The problem is even more serious than I expected. All subsequent tests will be silently skipped. Even if the test itself worries about this problematic behavior, any third-party library that is used in the code can cause trouble and completely disable testing.

test('example', () => {
  externalLibFail()
})

test('example2', () => {
  throw new Error("It will never be called")
})

function externalLibFail() {
  throw "not an Error"
}

Just encountered this behavior after few years of using uvu, this is very unexpected and very unpleasant :(

I've looked through other issues and found out, that author knew about this behavior since 2021, but did nothing (not even changed documentation) — https://github.com/lukeed/uvu/issues/130#issuecomment-896377702
