Getting unhandledRejection due to missing await keyword

[dekelev]

The call to the solver.decodeReCaptcha method is missing an await keyword, so any error in it (e.g. 504 Gateway error) will not be caught as expected and will lead to unhandledRejection in the NodeJS process.

After adding the await keyword (and the async keyword on the returned method), an error is thrown as expected, but the end result object that is returned to the client, has the Captcha in the solved array in addition to the error property, which is not consistent with the behavior of the puppeteer-extra-plugin-recaptcha. Expected behavior is that the solved array will be empty when an error is thrown.
