Context

If a test is skipped at runtime (with this.skip();), the test result gets overwritten, and all the data (links, labels, etc) is lost.
In such cases, onTest is called before onPending so there is no need to create a new test result.

Also, we might want to implement a countermeasure of some sort (a warning or an error) if we dismiss the currently running test result.

Other changes

• Issue template was added for allure-mocha.
• The runner parameter is now added to allure-mocha test results (we test against three types of runners: the CLI runner and two code runners, in the CommonJS and ESM formats).

Fixes #457
