FIX: General Cleanup & Recording Fix (Again...)

[seamus-sloan]

What's New?

There were a lot of squiggly lines from Pylint that needed to get handled. This involved some reordering of imports, adding doc strings, and renaming variables. Some Pylint warnings were suppressed in each file (Docstrings don't need to be added to test functions if the tests are named correctly).

Recording was tweaked (again...) since the issue was able to be reproduced on my Pixel 4 XL. I believe the issue is now about waiting for the device to save the video file to the location -- not the location itself. I do prefer the /data/local/tmp directory to the /sdcard/ directory, though, so that has stayed the same.

After adding another sleep to the record() function and allowing the user to have the option to delete the recording from the device, the record tests needed to be updated to account for the extra sleep and another test was added to ensure that the delete call is ONLY called when the user specified it to.

Checklist

• Tests pass?
• App runs?
