Ability to save a worklog without the hours

[rique-richter]

It would be nice to have the hability to add a worklog even tough you can't send it to Jira with only the Jira Issue and a comment, this way It's easier to remember I was working on that task even tough I don't know how much time I spent on it.

As a user,
I want to save the jira issue and a comment of what I was working on without the hours spent,
So that after I finish the task I can update the hours spent and save it to Jira.
