Persistent "Running git stash list..." message in status bar

[Keisuke Tada]

I've noticed a persistent message "Running git stash list..." appearing in the status bar whenever a file is open in the editor, following the changes made in #275 .

The change seems beneficial, but in my environment, the message continues to display. I am not sure whether the content of the message is accurate, but its continuous display seems odd. I am unsure if this is a bug, but I decided to raise this issue.

Thanks for reporting. There was a missing dispose(). Fix released in v0.6.47
