Fixed timeline for uploaded trace + dump files.

Now when uploading and opening trace and dump files at the same time, the timeline should be fully interactive in Global, Focused and Targeted modes. Timestamps should appear and change as you click along the timeline.

Test: Start a trace. Run a dump on another Winscope instance. End the first trace. Download the files from both instances, upload and open them on a separate instance. Check that the timestamp changes when selecting different parts of the timeline in different modes.
