Mahmoud Al-Qudsi a9278f654b Fix exception editing cross-wiki redirects
As described in T326169, when editing a (manually created) cross-wiki redirect,
VisualEditor will throw a null dereference exception causing it to fail to load
in the browser (looking like it is just taking forever to load).

This patch prevents the exception from occurring by not attempting to write to
the null object.

VisualEditor

VisualEditor provides a visual editor for wiki pages. It is written in JavaScript and runs in a web browser.

It uses the Parsoid parser to convert wikitext documents to annotated HTML which the VisualEditor is able to load, modify and emit back to Parsoid at which point it is converted back into wikitext.

For more information about these projects, check out the VisualEditor and Parsoid pages on mediawiki.

Developing and installing

For information on installing VisualEditor on a local wiki, please see https://www.mediawiki.org/wiki/Extension:VisualEditor

For information about running tests and contributing code to VisualEditor, see CONTRIBUTING.md. Patch submissions are reviewed and managed with Gerrit. There is also API documentation available for VisualEditor.
