code_scanner executes twice

[5h3rr1ll]

When scanning a code at http://localhost:8000/code_scanner/ (codeScanner/templates/codeScanner/code_scanner.html) the scanner should pause after recognizing a code and sends that code to the scraper at http://localhost:8000/lookup/CODE (scraper/views.py). The problem is that the scanner sends the same code twice, so the scraper also runs twice with the same code.

The scanner should only scan one code and send one code to the scraper.
