Fix a few of our failing ci issues

g_queue_clear_full was added in 2.60 but we only require 2.40

clang-format some files that were missing it.

Clean up the paths variable from command line parsing

Fix some leaks that the signal test caused and found

Testing Done:
Ran the valgrind convey plan. It still fails, mostly related to https://issues.imfreedom.org/issue/GPLUGIN-117.
