analysis server stalls if the same view is opened in multiple panes

[guillermooo]

ST has a bug where the .on_modified(view) event handler will be passed the wrong view if:

• the same file is opened in multiple views (using multiple panes)
• one of those views is active
• the active view isn't the first one that was opened

In this scenario, the analysis server doesn't get notified about changes to the view being edited.

This seems to be fixed now, but let's keep this open until we can verify the fix.
