[ZEPPELIN-2963] Fix paragraph aborting on next run after cancel
### What is this PR for?
As mentioned in ZEPPELIN-2963, if a paragraph is cancelled while it was in
scheduler's waiting queue, the next run of the paragraph always ends up in
abort status. This change fixes this issue.
### What type of PR is it?
Bug Fix
### Todos
### What is the Jira issue?
https://issues.apache.org/jira/browse/ZEPPELIN-2963
### How should this be tested?
The scenario that we want to reproduce is that a paragraph in the notebook
should be cancelled when it is still in the remote scheduler's waiting queue.
This can be reproduced in various ways. Following is the approach that I used:
1. Start zeppelin server.
2. Create a notebook with around 10-15 paragraphs with a few paragraphs
being long running (at least a few seconds)
3. Do a "Run All" on the notebook
4. Cancel the last paragraph (non-empty) by clicking the "Pause" button. It
will move to abort status.
5. After all paragraphs finish running, run the cancelled paragraph again.
It should start running.

* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
