UnhandledPromiseRejectionWarning: TimeoutError: Navigation timeout of 30000 ms exceeded

[DrHaze]

Bug

Exception raised due to timeout when loading pages. This is due to the default 30s timeout when awaiting a page. Currently living in France I'm far away from NZ and with an average internet connection. The startup of the application to the login screen takes more than 30s.
This is probably the same issue as: #107

Possible solution

To fix the issue on my side, I globally removed the navigation timeout:

        // Use current page
        const page = (await browser.pages())[0];

        await page.setDefaultNavigationTimeout(0); 
        await page.setUserAgent('Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36');

I should probably do a merge request for that but I first started by downloading the zip of the repo and editing the file using notepad... Let me know if you want one.
