Fix refresh token logic

[alfespa17]

This will fix the refresh token logic when using a new bitbucket connection that is using the custom callback feature.

The logs will show something like this:

2023-09-26 20:00:00.035  INFO 1 --- [ryBean_Worker-8] o.t.api.plugin.scheduler.ScheduleVcs     : VCS found with custom callback
2023-09-26 20:00:00.036  INFO 1 --- [ryBean_Worker-8] o.terrakube.api.plugin.vcs.TokenService  : Renew Token before: 2023-09-26 21:00:00.83 88faf1f1-3c6f-42ad-8865-ed98919ba2d1
