Theme filetype icons applied only intermittently to external folders

[tipichris]

Steps to reproduce

1. Create a theme with alternative icons for filetypes
2. Configure OC to use it
3. Run occ maintenance:mimetype:update-js
4. View a file list

Expected behaviour

File icons should be those from the theme

Actual behaviour

Most file icons are those from the theme. However, those for external folders are from core.
In fact, the new icon seems to display momentarily, then the row is greyed out briefly and when it is un-greyed the icon is that from core. Various changes that result in ajax calls also result in the icon being changed to that from the theme, for example, marking or unmarking the folder as a favourite.

It appears that some sort of dom manipulation is going on for external folders shortly after the file list loads and this is not respecting the theme. Further dom manipulation does respect the theme and changes the value of the elements background URL accordingly.

If you see it appearing and being replaced, I suspect it's the "external storage availability check" code that replaces it with the wrong icon and doesn't use the theme.

It looks like the problem lies in OCA.External.StatusManager.Utils.getIconRoute

This patch sorts the immediate problem out for me, but it looks as if there would still be problems sharepoint and Windows Network Drives

The code isn't the same as the one for 8.2, and that part is something that changed between versions, so I'm not going to be of help here...

Anyway, the patch make sense. The only thing "weird" is the name of the icon. I'm not sure if the one from the theming should match with the default one (dir-external -> folder-external).
Regarding sharepoint and WND icons, I'm not sure if they're themeables, but there shouldn't be any change with the patch anyway.

@tipichris could you make a PR with the patch so we can review and test it?

[tipichris]

@jvillafanez PR done. dir-external is not the name of the icon. I guess you could call it a pseudo-mimetype. It gets fed to OC.MimeType._getFile which returns the icon file name, folder-external.
