[BUGFIX] Catch errors in upload form

The upload forms failed to catch errors due to a
never matching condition. Failing uploads (eg. because of
filesize limit etc.) still tried to render non-existing
download links instead of showing the error.

Fix the condition by testing if the return string
starts with "Error" instead of equals "Error".
