[ReviewEntries] Can save sense edits multiple times

[imnasnainaec]

Describe the bug

In Review Entries, in the Edit entry dialog, the save button can be clicked multiple times.

To Reproduce

1. Go to Review Entries
2. Click on the edit pencil icon at the start of one of the rows
3. Scroll down to Pronunciations and add an audio recording (or several)
4. Multi-click on the green check in the upper corner
5. There was a console.info(file); accidentally left in the code for debugging, but because of that, the console will show every time the save is attempted.

Expected behavior

The save/close buttons should be disabled while waiting for the save to complete.
