Submission review status error message should disappear once the status selected

[manjitapandey]

Describe the bug
Following from the issue #1617 , if user add a comment on submission without adding the submission status, an error message is shown saying "Review status needs to be selected". However, even after selecting the submission status , the error message is not removed.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'submission details page'
2. Click on 'Update review status'
3. add comment without adding review status
4. Again change review status
5. See error

Expected behavior
The error message should be cleared, once the review status is added.

Screenshots

Additional context
The addition of comment without adding review status is not an ideal user behavior so I am adding this issue on low priority.

Also would it be okay if we disable the submit button unless the review status is added?

The update button is disabled until the submission status is selected.
