After updating an app, the ownCloud instance is loading old app's js file

[davitol]

When you install an app using the CLI (occ market:install), the new version of market app is installing under apps-external folder which folder is the writable one in the config.php and the old version is still remaining under apps folder. That is the expected behavior due to 'writable' => false means "nobody can change anything in this app directory".
See the expectations in #35031

After the installation the ownCloud instance is somehow loading old app's js file. If you remove the old app from apps folder, the problem is solved
