refactor: Removed check active editor from model (#443)

[edgardmessias]

My idea to improve model.ts:

• Create more events (When necessary)
• Move code to another files and use events

[JohnstonCode]

How do we use contexts?

[edgardmessias]

Used to show/hide "Open changes BASE/HEAD" in editor

Here:

svn-scm/package.json

Line 424 in 69aa2bf

"when": "config.svn.enabled && svnOpenRepositoryCount != 0 && svnActiveEditorHasChanges"

svn-scm/package.json

Line 798 in 69aa2bf

"when": "config.svn.enabled && svnOpenRepositoryCount != 0 && svnActiveEditorHasChanges && !isInDiffEditor && resourceScheme == file"
