Marking task as done and then saving file resets status to pending

[brendanator]

If I run :TaskWikiDone and then save the file the status is reset to pending

Here's the info on the task

2018-04-30 08:50:54 End set to '2018-04-30 08:50:54'.
                    Status changed from 'pending' to 'completed'.
2018-04-30 08:50:56 End deleted.
                    Status changed from 'completed' to 'pending'.

There was a second viewport also containing this task in the file that was overwriting the change

This is definitely an issue as I might easily want to have the task appear in 2 viewports.

Making a change to any view of a task should propagate to the others

I was having this problem as well, but with one task that was not in a viewport and one that was in a viewport in the same file. The viewport task seemed to always take precedence over the free floating task, but maybe that was just an order effect? My viewport came after the plain vimwiki task list.

Made a patch to fix this. Let me know your comments.

@nagakiran Maybe we should convert this to a proper PR?

This is actually another case of the same problem as #113

This patch appears to work for modified tasks. But if a task is deleted it pops back into the viewport.
