Describe the bug

When launching the ownCloud client build from the most recent sources, the client displays an update notification stating that a new version (exactly equal to that which was build) is available. The "Updates" section in the "Settings" tab also notifies the user of this supposedly newer version.

Expected behavior

If the client was built from the most recent source release, no update notification should be displayed and the "Settings" tab "Updates" section should not say that a new version is available with the exact same version and build number.

Steps to reproduce the issue

1. Open ownCloud client
2. Observe update notification being displayed
3. Open "Settings" tab
4. Scroll to "Updates" section
5. Observe notice about newer version being available with same version identifiers

Additional context

This is probably also one of the main use cases for the "skipUpdateCheck" option described in #5814 (comment). I've also had this issue with Arch builds

I'd recommend to build the client with "-DWITH_AUTO_UPDATER=OFF".
For 4.0 the parameter will default to off.
