Status changed on entry edit based on user permissions

[robinsowell]

Description of the problem
Member group 'a' only has permission to post in 'Pending' status. They post, superadmin checks it, switches status to 'open'. Works fine. But if the group 'a' edits, the status reverts to 'Pending'. It shouldn't disallow an existing status based on the member's permissions.

How To Reproduce
Steps to reproduce the behavior:
See above

Environment Details:

• Version: [e.g. 5.3.2]
• PHP Version [e.g. 7.1]
• MySQL Version [e.g. 5.7]
• OS: [e.g. Linux, macOS, Windows]
• Web Server: [e.g. Apache, nginx, MAMP, etc.]

@robinsowell I think this might be subject for discussion. I believe the idea behind this behaviour might be intentions - after member edits the entry, it's pending again and requires approval because the changes have been made

@TomJaeger need your input here

Same, or very similar issue, has been reported in #1877

Copying over my comment from there:

In short, the situation might occur when member has permissions on the channel, but does not have permission to the status that the entry has. While this might be intentional, we probably need to show them a warning that the current status might be lost.
