Fixes#8788
- Fixed missing argument lists on constructors, and improved handling for various cases of partially applied functions.
- Extended tests to check for correct `self` argument placeholders.
- Additionally reworked some questionable test code to maintain separation between server and client code.

Further AST integration and API refinement before introducing the new synchronization mechanism.
closes#8609
# Important Notes
API changes:
- Renamed `Ast.parseExpression` / `Ast.parse` to better reflect their usage:
- `Ast.parse` returns a block or a single expression, depending on its input; this is convenient for expressions expected to be single-line.
- `Ast.parseBlock` always treats its input as a block; this is suitable for parsing a file.
- `astExtended` is no longer needed to access span information. `Ast.span` provides access to the value when appropriate (the project's committed modules have spans; uncommitted changes or other parsed expressions don't).
- `SourceRange` is now used everywhere in place of `ContentRange`--the two types had the same definition.
Features:
- Fix CodeEditor viewing.
Implementation improvements:
- Updated widget update handlers (#8545) implementation to Ast API.
- Integrated `imports` more thoroughly with new AST APIs.
- More tests.
- Closes#8398
# Important Notes
- The original error caused by a failing `text/openFile` (`openTextFile`) is still present, but (seemingly?) harder to repro now
