Files cannot be cloned in Windows

[zane-perry]

Any file in the folder tests/previousresults/ with a ':' in its title causes an error because windows files cannot have that symbol in its name

These are all test files. We can change the filenames, but we need to change the test script to use these new names. May not be too hard. Perhaps just change to a symbol that is okay for windows in the files and test script.

Change compare_request to sanitize "file_path". Update test files using the same symbol that you replace ":" with.
