Tracked time being overridden

Hi,

Thanks for making this extension @shridhar-tl , it's the best way I've found to log time to JIRA. However, I have just found a bug.

I track time against tickets in multiple batches - e.g. I'll record on worklog entry of 4 hours against a ticket and then another of 1 hour. When I view the ticket in JIRA it only shows the "time spent" as being 1 hour though, not the 5 hours I expect.

Here's what Jira Assistant shows: captura de tela 2018-07-10 as 14 57 53 1

And here's the ticket in JIRA: ticket_in_jira.
