bug-fix: mo uninstall unbound variable on empty tuples (#352)

Browse Source 
This happens when no third party app is available to be uninstalled; this triggers an `unbound variable` on the app_data_tuple causing the utility to fail.

This is caused mostly because the bash version is 3.2 on MacOS; it seems that since Bash 4 this unbound_variable is set to 0 and would have not went to that error.

Added an alternative value in case of error of 0 for this topic. This should handle this corner case
