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.

GPlugin is a GObject based library that implements a reusable plugin system.
It supports loading plugins in multiple other languages via loaders. It relies
heavily on [GObjectIntrospection](https://gi.readthedocs.io/) to expose its API
to the other languages.
It has a simple API which makes it very easy to use in your application.
For more information on using GPlugin in your application, please see the
[embedding](https://docs.pidgin.im/gplugin/latest/chapter-embedding.html) page.
## History
GPlugin has a bit of history, you can read more about it in [HISTORY.md](HISTORY.md)
## Language Support
GPlugin currently supports plugins written in C/C++, Lua, Perl5, Python3, and
Vala.
## API Reference
The in-development API reference for the development branch can be found at
