The default content-security-policy of ownCloud forbids inline
JavaScript for security reasons. IE starting on Windows 10 will
however also obey the CSP which will break the event source fallback.
As a workaround thus we set a custom policy which allows the execution
of inline JavaScript.
This fixes #14286
Backport of #17791
