Did you use PaperUI to install and then uninstall the binding or it was manually installed (placing the *.jar file in the /usr/share/openhab2/addons folder) in the first place?
You could try the following:
Enter into Karaf console with: ssh openhab@localhost -p 8101 with password: habopen
and then:
bundle:list
or
bundle:list |grep mios
bundle:uninstall <ID>
