fix(execute): Handle async opts

[gabrielferreira-imi]

Fixes #237

@gabrielferreira-imi code looks good can you add a test to confirm that the execute command is stored and called after hCaptcha onload is executed.

Thanks @gabrielferreira-imi!

Need to add one more test to verify the onload callback will also process the ready function correctly. Once that is done, can you bump the version in the package.json?

@zoryana94 mind confirming on your end that all is good as well?

Facing the issue while executing hCaptcha on the component mount
Suggested changes seem to fix it!

[zoryana94]

it looks like const hcaptcha = this._hcaptcha; needs to be also added inside of the this._onReady function
after making this change, it seems to start working:

this._onReady = (id) => {
      try {
        const hcaptcha = this._hcaptcha;

        if (opts && opts.async) {

otherwise, I receive this when executing hCaptcha on the component mount:

opts !== null check seems to be redundant
as opts are set to null anyway

opts = typeof opts === 'object' ? opts : null;

Tested on multiple test apps
Should be good now, @gabrielferreira-imi 👍
