Plasma Integration extension injects its own scripts into pages where inline scripts are disallowed by Content Security Policy, which promptly get blocked by a browser, and then in pages where 'report-uri' directive is present browser sends two reports for every page, which causes the server-side reports log to be cluttered with violation reports caused by the extension.

Steps to Reproduce:

1) Install Plasma Integration extension.
2) Go to page where Content Security Policy does not allow inline scripts, e.g. https://wandystan.eu/w/.
3) Open browser console.

Actual Results:

There are two errors like this:

> Content Security Policy: Ustawienia strony zablokowały wczytanie zasobu „self” („script-src https://wandystan.eu”). Source: (        function() {            f4207....
> Content Security Policy: Ustawienia strony zablokowały wczytanie zasobu „self” („script-src https://wandystan.eu”). Source: (function() {            var oldCreateE....

And two requests to report URI such as https://wandystan.eu/varia/csp_report.php are sent.

Expected Results:

There are no errors and no violation is reported.
