Integration tests for XOAuth2

[imartinezortiz]

Hi, although during the development I realized that the refresh_token is the only relevant secret regarding the XOAuth2 authentication, I just verified that I could run ./integration-test.sh xoauth2 with the token file that I had since last week. So I think that you can enable integration tests by:

1. Login once with the testing account to obtain refresh_token and access_token
2. Store these secrets as github secrets.
3. Generate the .env with using the stored secrets to initialize XOAUTH2_INITIAL_ACCESS_TOKEN and XOAUTH2_INITIAL_REFRESH_TOKEN.

Although in a proper installation these variables are only used once to initialize the internal token database, seems that the XOAuth2 library can refresh the access_token without problem.

Lovely, I'll check.

What I did initially (and didn't work):

• get RT and AC
• run tests (ok)
• wait a bit over an hour
• run the tests again (tests failed this time)

I haven't explored further, but you might be right -- I'll check.

Yesterday I setup (with the same secrets) a instance of the latest container in a different machine and it worked. The only thing it is that I have enabled 2FA for that account.
