Very minor - clean up extraneous whitespace

[Next-Door-Tech]

This is an incredibly minor pull request - no actual changes to the code were made. This is just stuff that Atom does automatically for you when saving a file, just wanted to pull this separately to mitigate diff spam for other requests.

Summary:

• Removed spaces/tabs in lines that had only spaces or tabs (i.e. those left over when deleting an indented line)
• Added a newline to end of file when missing
• Removed unneeded spaces at the end of a line of code
