Remove drag and drop functionality, no more empty tables created on every save

Please use an issue fork and merge request. Please use the issue summary template.

Updated the issue summary and added an extra paragraph at the bottom for context.

I don't think it's appropriate to make a MR at this time.

What is to be reviewed? The issue summary makes this look like a duplicate of 🐛 Empty tables are being saved to the db if a tablefield is empty Active . Is this issue just reporting the temporary work-around?

The workaround patch has been working for me for a while now, but it hasn't been tested by anyone else. I wouldn't say it is fixed, or RBTC, but neither is it active or needs work. Needs review seemed the best status as it indicates that the functionality is considered to be complete but has not been verified by a second party.

I considered putting the patch in issue 3490590, but any discussion about it would seem off topic to a proper solution. 3490590 was linked as a related issue to this one.

To be reviewed for commit, the change need to be in a merge request. The issue summary needs to describe what this issue is about, not just link to another issue. If the issue description is in another issue, it should be resolved in that issue.
