Describe the bug
The launcher application will crash and restart if a notification is removed using the API instead of through the UI.

To Reproduce
Steps to reproduce the behavior:

1. Open the launcher and run the following

text="Hello World!"
uuid=$(cat /proc/sys/kernel/random/uuid)
path=$(rot notification call add \
        "QString:\"$uuid\"" \
        'QString:"sample-application"' \
        "QString:\"$text\"" \
        'QString:""' \
    | jq -cr \
    | sed 's|/codes/eeems/oxide1/||'
)
# remove notification
rot --object Notification:$path notification call remove

2. Launcher will crash and restart.

Expected behavior
The launcher should not crash.
