Popup broken/disabled since `mdpopups` 4.3.0

[rudiedirkx]

A few days ago mdpopups 4.3.0 came out, and Package Control updated it, and then the GitGutter popup didn't work anymore.

I added in modules/popup/__init__.py:

 except ImportError:
+    print("gitutter popup ImportError")
     show_diff_popup = None

and yes, that's logged, because the import mdpopups itself doesn't work.

I'm running a very old ST (version 3.1.1, build 3176), but it has always worked. Did mdpopups break something, or is gitgutter too strict, or is this the inevitable result of me not wanting to upgrade?

If I revert mdpoups back to 4.2.2 everything works again, BUT ST/Package Control immediately wants to upgrade it to 4.3.0 again 🤦 even though I disabled upgrades in PC.
