Error handling for suit visitor

[eudgen-dev]

Hi,

Please add error handling for @BeforeAll, @AfterAll, @BeforeEach, @AfterEach methods

Version: 2.0.0-beta.7

ex:

@TestSuite()
export class TestSuit {
  @BeforeAll()
  async beforeAll() {
    throw new Error('Some error');
  }

  @Test()
  public test() {
    ok(true);
  }
}

The output is:

Root
TestSuit
Summary: 0/1 passed, 1/1 failed, 0/1 skipped. (0s)

There are any info about the exception
