Multiple mounts when restarting service

[keab]

I have installed spotify-connect-web on an RPI1 with OSMC. If I stop and restart the service using systemctl I noticed that I get duplicate mounts of /proc and /dev. Not pretty.
My solution was to modify spotify-connect-web.sh and replace
sudo mount --bind /dev $DIR/dev
sudo mount -t proc proc $DIR/proc/
with
if ! mount | grep -q "$DIR/proc" ; then sudo mount -t proc proc $DIR/proc/; fi
if ! mount | grep -q "$DIR/dev" ; then sudo mount --bind /dev $DIR/dev;fi

I don't know if this is the best solution but I suggest that some solution should be implemented.

I'll see about adding some checks for existing mounts
