Nextcloud-client snap missing panel icon

[bashfulrobot]

Hi there. When using the nextcloud-client snap, the icon is missing on Linux.

• Ubuntu Budgie 18.04 and 17.10.

• snap 2.30

• snapd 2.30

• series 16

• ubuntu 18.04

• kernel 4.13.0-32-generic

This repo is for the Nextcloud server snap. This one is for the client snap.

That said, this works fine for me on Ubuntu Desktop 16.04:

This is also a problem for me on Ubuntu-Mate 18.04.
