Roan Kattouw 0c92ef904c Followup 5c0c117: make the edit tab work with oldid= again
After 5c0c117, clicking the VE edit tab on /wiki/Foo?oldid=123
sent you to /wiki/Foo?veaction=edit , dropping the oldid parameter
and editing the current version rather than the old version.

Fix this by only recomputing veEditUri from scratch when necessary,
and reusing the current URI when possible.

* Add a plugin module or function.
*
* Plugins are run after VisualEditor is loaded, but before it is initialized. This allows
* plugins to add classes and register them with the factories and registries.
*
* The parameter to this function can be a ResourceLoader module name or a function.
*
* If it's a module name, it will be loaded together with the VisualEditor core modules when
* VE is loaded. No special care is taken to ensure that the module runs after the VE
* classes are loaded, so if this is desired, the module should depend on
* ext.visualEditor.core .
*
* If it's a function, it will be invoked once the VisualEditor core modules and any
* plugin modules registered through this function have been loaded, but before the editor
* is intialized. The function takes one parameter, which is the ve.init.mw.Target instance
* that's initializing, and can optionally return a jQuery.Promise . VisualEditor will
* only be initialized once all promises returned by plugin functions have been resolved.
*
* @example
* // Register ResourceLoader module
* ve.libs.mw.addPlugin( 'ext.gadget.foobar' );
*
* // Register a callback
* ve.libs.mw.addPlugin( function ( target ) {
* ve.dm.Foobar = .....
* } );
*
* // Register a callback that loads another script
* ve.libs.mw.addPlugin( function () {
* return $.getScript( 'http://example.com/foobar.js' );
* } );
*
* @param {string|Function} plugin Module name or callback that optionally returns a promise
