Modules: Avoid error when calling an uninstall function with "DROP TABLE"

[blackcoder87]

Describe the bug
Calling the uninstall function of a not installed module can cause an error if "DROP TABLE" is used. "DROP TABLE" without the "IF EXISTS" clause throws an error if the table doesn't exist. You might want to call the uninstall function of a module to make sure there are no leftovers of a failed module install in the database.
